Tech Tip: Mazda Front Brake Clunking Noise

When braking in a forward direction, then changing direction and braking in reverse, a clunk noise may be heard from the front brakes. This condition is most noticeable when the vehicle is moving forward, then backward a short distance while applying the brakes in both directions. The clunk noise may be caused by excessive clearance between the brake pad and caliper support.

Customers having this concern should have their vehicle repaired using the following procedure.

Repair Procedure:

1. Verify the customer concern.

2. Remove the front brake pads and shims from the caliper.

Caution: Avoid damage or deformation of existing shims because they will be re-used.

3. Preassemble the modified pads with the existing shims. See Fig. 1.

Fig. 1
Note: Replace the brake pads only; the original shims must be re-used.

4. Install the brake pads with original shims to the caliper support.

Note: Ensure brakes are free from dragging or ­unusual noise.

5. Verify the repair.

Adjusting Parking Brakes

You should never estimate when it comes to parking brake adjustments.

The parking or emergency brake has to perform two distinct jobs. First, it must be able to hold the vehicle on an incline. Second, it must be able to stop a vehicle under a specific distance if the hydraulic brakes have failed. These standards are set by the Department of Transportation (DOT), and the kicker is these standards must be met with the force applied by a little old lady. But, over time, the cables can stretch and the friction materials change their length and thickness, which is why adjustments to the system are required.

When you think about the braking system of a vehicle, you probably think about the major parts you see when removing the wheel: brake pads, rotors, calipers and maybe hydraulics. However, one of the most important parts of the system isn’t visible: brake fluid. Brake fluid comes in several formulations for different applications and plays
