Description:
The bracket provides a mounting support TDA H59 3299Q6257 for the brake chamber (actuator) and interfaces with a camshaft / slack adjuster in the air brake assembly. It helps maintain proper alignment, stability, and absorbs mechanical load / vibration. Air Brake Chamber Bracket, work condition, used take-off. 

Specifications TDA H59 3299Q6257:

Brake Type: CQN419 Cam Brake
Mounting Location: Right Hand Side
Pallet Quantity: 24
Slack Adjuster Length: 5.50 to 6.00 in
Camshaft Barrel Length: 10.70 in


Purpose of using TDA H59 3299Q6257:

The brake chamber uses compressed air to push a pushrod.

That pushrod connects to a slack adjuster, which turns a camshaft (S-cam).
The camshaft rotates, spreading the brake shoes against the drum.
The bracket holds the brake chamber and camshaft in place, ensuring they stay aligned and can transfer force effectively.

Without this bracket:

The air brake system would have nothing to anchor to
The forces from braking would twist or misalign the components
Braking would be inconsistent or fail entirely


Signs of a Faulty Air Brake Chamber Bracket TDA H59 3299Q6257

Excessive play in the S-camshaft
Uneven braking
Cracks or fractures around mounting holes
Misalignment between the brake chamber and slack adjuster
Worn bushings (camshaft rattles or moves)
