Overview

The ConMet TruTurn is a premium cast-iron brake drum designed for commercial trucks, tractors, trailers, buses, and vocational vehicles. It is available in multiple part numbers covering steer, drive, trailer, and specialty wheel-end applications.

TruTurn’s defining feature is ConMet’s turned-to-balance manufacturing process. Instead of adding welded balance weights or cutting isolated areas from the drum, ConMet machines more than 95 percent of the drum’s interior and exterior surfaces.

This process produces a more uniform wall thickness and makes the drum inherently balanced. The uniform structure helps distribute heat more evenly while reducing vibration, brake pulsation, and uneven friction-material wear.

Eliminating welded weights and aggressive balance cuts also preserves more of the drum’s original structural integrity. The result is a premium drum designed to provide consistent braking, lower operating temperatures, and long service life.

TruTurn is a product family rather than one universal brake drum. Each part number has its own brake diameter, lining width, mounting type, pilot diameter, bolt pattern, offset, overall depth, weight, axle position, and maximum wear diameter.

ConMet continues to identify TruTurn as its top-tier brake-drum offering. In 2026, the company added the broader aftermarket TruCast line while retaining TruTurn for customers seeking premium performance and manufacturing quality. ConMet brake components

How the Brake Component or System Works

The TruTurn drum mounts to the wheel hub and rotates with the wheel. When the driver applies the service brakes, compressed air enters the brake chamber and moves the pushrod.

The pushrod rotates the slack adjuster and camshaft. The S-shaped cam head spreads the brake shoes outward until their friction linings contact the drum’s internal braking surface.

Friction between the stationary linings and rotating drum slows the wheel. The vehicle’s motion is converted into heat that is absorbed by the drum, friction material, hub, wheel, and surrounding air.

TruTurn’s uniform wall thickness helps distribute this heat around the drum. More even heat distribution can reduce localized hot spots, distortion, pulsation, and thermal stress.

When the brake releases, the shoe-return springs pull the linings away from the drum. The TruTurn continues rotating with the hub without intentional friction contact.

Position and Function Within the Brake System

The TruTurn is installed at the wheel end over a compatible S-cam foundation brake. Its specific position depends on the selected part number.

The drum performs several essential functions:

  • Provides the friction surface for the brake linings
  • Absorbs heat created during braking
  • Releases heat into the surrounding air
  • Transfers braking torque through the wheel end
  • Maintains the required geometry around the brake shoes
  • Helps protect internal brake components
  • Supports balanced rotation of the wheel-end assembly

The drum does not independently create or control brake pressure. Its performance depends on the brake chamber, slack adjuster, camshaft, shoes, friction material, air system, ABS, hub, wheels, and tires.

Operating Specifications and Performance

TruTurn’s machining process is designed to produce consistent wall thickness around the drum. Uniform material distribution helps the drum rotate smoothly and absorb heat more evenly.

ConMet identifies several operational benefits:

  • Improved drum strength
  • Reduced brake pulsation
  • Lower operating temperatures
  • Reduced vibration
  • More consistent braking
  • Maximum durability
  • Longer potential component life

These benefits depend on the correct drum being installed on a properly maintained brake and wheel end. Actual performance varies with vehicle loading, route, braking frequency, friction material, drum size, brake balance, ambient conditions, and driver behavior.

The maximum diameter cast or marked on the drum is the controlling wear limit. If any part of the friction surface exceeds that dimension, the drum must be removed from service.

A TruTurn drum does not raise the vehicle’s certified gross axle weight rating. The axle, hub, wheels, tires, suspension, and complete brake system must support the application.

Braking Performance and System Integration

TruTurn works as part of a complete S-cam foundation-brake system. Drum balance and dimensional consistency can improve brake smoothness, but proper braking still depends on the surrounding components.

The complete system includes:

  • Air brake chamber
  • Pushrod and clevis
  • Slack adjuster
  • Camshaft
  • Brake spider
  • Rollers and anchor pins
  • Brake shoes
  • Friction linings
  • Shoe-return springs
  • Wheel hub
  • Bearings and seals
  • ABS components

A damaged chamber, excessive pushrod stroke, worn camshaft, contaminated lining, or incorrect friction material can reduce braking performance even when the drum remains serviceable.

Drums and friction material should be matched across an axle. Significant differences in diameter, surface condition, or friction formulation can create unequal braking torque and temperature.

Air Supply, Controls, and Electronic Integration

The TruTurn has no direct pneumatic or electronic connections. It responds to mechanical force generated by the air brake system.

It can operate within systems equipped with:

  • Service brake chambers
  • Spring-brake chambers
  • Automatic slack adjusters
  • Manual slack adjusters
  • Relay valves
  • Antilock braking systems
  • Automatic traction control
  • Electronic stability control
  • Trailer roll-stability systems
  • Wheel-speed sensors
  • Electronic brake-stroke monitoring

ABS controls air pressure when wheel lockup is detected. It cannot compensate for an oversized, cracked, contaminated, distorted, or incorrectly installed drum.

Electronic stability systems may selectively apply individual brakes. Their performance still depends on serviceable drums, linings, chambers, valves, sensors, tires, and wheel ends.

Installation, Adjustment, and Brake Balance

The TruTurn must match the axle, hub, wheel, foundation brake, and mounting configuration. Installation should follow ConMet’s service procedures and the vehicle manufacturer’s torque requirements.

Important installation checks include:

  • Confirming the complete ConMet part number
  • Verifying brake diameter and width
  • Confirming steer, drive, or trailer position
  • Checking inboard or outboard mounting
  • Confirming the pilot diameter
  • Checking the bolt-circle diameter
  • Verifying bolt-hole number and size
  • Checking drum offset
  • Confirming overall depth
  • Inspecting the hub pilot
  • Cleaning the mounting surfaces
  • Inspecting wheel studs
  • Measuring drum diameter
  • Inspecting the braking surface
  • Checking brake shoes and friction material
  • Following the proper wheel-fastener sequence
  • Tightening fasteners to specification
  • Measuring applied pushrod stroke
  • Comparing brake operation across the axle

The wheel or wheel nuts should never be used to force an incompatible drum onto the hub. Improper seating can create runout, vibration, cracking, and wheel-end looseness.

Foundation Brake, Axle, and Wheel-End Compatibility

TruTurn drums are available for many commercial wheel-end arrangements. Compatibility depends on the complete drum geometry rather than nominal brake size alone.

The correct part must match:

  • Axle manufacturer
  • Axle model
  • Axle position
  • Gross axle weight rating
  • Hub manufacturer
  • Hub model
  • Hub-pilot diameter
  • Bolt-circle diameter
  • Number of bolt holes
  • Bolt-hole diameter
  • Drum offset
  • Overall depth
  • Brake-surface width
  • Foundation-brake diameter
  • Wheel mounting system
  • Wheel size and offset
  • ABS component clearance
  • Vehicle brake certification

Certain ConMet drums are designed to accommodate either ball-seat or hub-piloted wheel systems through application-specific bolt-hole and pilot dimensions. This feature must be confirmed by part number rather than assumed.

TruTurn can also be paired with compatible ConMet Conventional, PreSet, and PreSet Plus hub systems when the wheel-end specification approves the combination.

Driver and Operator Experience

A properly installed TruTurn should provide smooth and predictable drum-brake operation. Its balance and uniform wall thickness are intended to reduce vibration and brake pulsation.

Drivers may notice smoother braking when replacing a distorted or poorly balanced drum. However, pedal response and stopping performance still depend on the complete pneumatic and mechanical brake system.

Drivers should report:

  • Brake pulsation
  • Steering-wheel vibration during braking
  • Vehicle pulling
  • Increased stopping distance
  • Brake fade
  • Burning odors
  • Wheel-end smoke
  • Grinding or scraping
  • Brakes that release slowly
  • ABS warning lamps
  • Low-air warnings
  • Excessive wheel-end heat
  • Parking brakes that do not hold

Uniform drum construction does not replace proper speed selection, engine braking, and safe descent procedures.

Maintenance and Ownership Notes

  • Inspect drums at scheduled intervals
  • Measure internal drum diameter
  • Check the cast maximum-diameter marking
  • Inspect for visible cracks
  • Check for heat checking
  • Inspect for blue or discolored areas
  • Check for hard spots
  • Inspect for scoring and grooves
  • Check for out-of-round wear
  • Inspect the mounting flange
  • Check the hub pilot
  • Inspect bolt holes
  • Check wheel studs
  • Clean mounting surfaces
  • Inspect brake shoes and linings
  • Check for friction-material contamination
  • Measure applied pushrod stroke

  • Replace damaged drums
  • Replace drums and linings in axle sets when required

Common Brake-System Problems

  • Cracked drum: Severe overheating, operation beyond the wear limit, overloading, improper mounting, corrosion between the drum and hub, or impact damage may cause cracking.
  • Brake pulsation: Drum runout, out-of-round wear, hard spots, improper seating, wheel-end looseness, or damaged mounting surfaces may create pulsation.
  • Uneven lining wear: Drum distortion, worn rollers, camshaft movement, incorrect shoes, or foundation-brake problems may prevent uniform contact.
  • Heat checking: Repeated heating and cooling can create small cracks in the friction surface. Heavy or spreading heat checks may require replacement.
  • Brake fade: Excessive temperature can reduce friction between the linings and drum during repeated or prolonged brake applications.
  • Deep scoring: Exposed rivets, worn linings, foreign material, or continued operation after friction material is exhausted can score the drum.
  • Glazed braking surface: Excessive heat, light repeated applications, or incompatible friction material can polish the drum surface and reduce friction.
  • Excessive pushrod stroke: Worn linings, an oversized drum, incorrect adjustment, worn camshaft components, or slack-adjuster problems may increase stroke.
  • Wheel-end vibration: Improper drum seating, hub problems, damaged wheels, loose fasteners, tire imbalance, or wheel-bearing looseness may cause vibration.
  • Drum will not seat correctly: Rust, debris, an incorrect pilot, incompatible bolt holes, damaged studs, or the wrong part number may prevent proper installation.
  • Brake pulling: Unequal drum condition, different friction materials, contamination, chamber problems, or pneumatic imbalance can cause side-to-side differences.

Safety and Service Precautions

Commercial brake drums are heavy and can remain dangerously hot after vehicle operation. Technicians should use safe lifting, supporting, and cooling procedures.

Before servicing a TruTurn wheel end:

  • Park on a firm and level surface
  • Chock the wheels
  • Drain or isolate air pressure as directed
  • Cage spring brakes when required
  • Never disassemble a spring-brake chamber
  • Support raised axles with approved stands
  • Allow hot drums to cool naturally
  • Wear eye, hand, and foot protection
  • Use appropriate drum-handling equipment
  • Control brake dust
  • Follow approved wheel-removal procedures
  • Use calibrated torque tools
  • Follow the specified tightening sequence

Never work beneath a vehicle supported only by a jack. Never rapidly cool a hot drum with water because thermal shock can damage the casting.

Brake dust should not be cleaned with compressed air. Approved cleaning and containment procedures should be used.

Regulatory and Compliance Notes

Commercial brake drums must remain within the manufacturer’s dimensional and structural service limits. The maximum diameter cast or marked on the individual drum controls its allowable wear limit.

A drum may require replacement if:

  • It is cracked
  • The back plate is damaged
  • Bolt holes are elongated
  • Heavy heat checking is present
  • It has been severely overheated
  • It is out of round
  • Deep grooves exceed allowable limits
  • Any portion exceeds the maximum diameter
  • Mounting surfaces are damaged
  • It cannot seat correctly on the hub

ConMet recommends replacing drums and friction components in matched axle sets when required to preserve balanced braking.

The drum’s physical capacity does not increase the certified axle or vehicle rating. The complete axle, hub, wheels, tires, suspension, foundation brakes, and vehicle certification remain controlling.

Real World Operating Notes

TruTurn’s smooth exterior is the result of its extensive machining process. It should not be mistaken for material removed solely to correct imbalance.

The turned-to-balance process distributes material uniformly instead of relying on welded weights or isolated balance cuts. Damage to the machined surface should still be evaluated before installation.

Drum measurements should be taken at multiple locations. A single reading may not reveal taper, bell-mouthing, or out-of-round wear.

Drums should be compared across the axle. A new drum opposite an oversized or heat-damaged drum can contribute to unequal braking.

A balanced drum cannot correct a damaged hub, bent wheel, loose bearing, imbalanced tire, or incorrect installation. The entire wheel end should be inspected when vibration occurs.

New drums and friction material should be burnished according to the brake or vehicle manufacturer’s procedure.
