Q:

How do you fix a frozen brake caliper?

A:

Solve most sticking brake caliper problems by replacing the existing caliper with a new one. The process requires removing the wheel and caliper, installing the new caliper, bleeding the brakes and reattaching the wheel. The process takes most of an afternoon.

  1. Remove the wheel

    Loosen the lug nuts, and lift the car with a jack. Finish removing the tire to access the caliper.

  2. Remove the defective caliper

    Place a drain pan under the wheel to catch any dripping brake fluid before proceeding. Remove the bolt that connects the brake line to the caliper. Remove the bolts, rubber boots and sliders holding the caliper in place. Drain any remaining brake fluid from the caliper. Inspect all slides for signs of rust or damage as reuse of these parts saves money.

  3. Install the new caliper

    Compress the new caliper completely using the caliper tool. Install the caliper, and attach the brake line to the new assembly.

  4. Bleed the brakes

    Fill the brake fluid reservoir with new fluid. Have a helper press and hold the brake pedal while you open the bleeder valve. Close the valve, and ask the helper to release the brake. Continue the process until no bubbles appear in the fluid from the brake lines.

  5. Reattach the wheel

    Put the wheel back on the car, and tighten the lug nuts. Lower the jack, and torque the lug nuts to the manufacturer's specification.

    What is the minimum thickness for a disc brake pad?

    A:

    The minimum thickness allowed for a disc brake pad is approximately one millimeter. A brake pad's standard thickness is between 10 and 12 millimeters. Because disc brake pads and rotors are vehicle parts that will wear down, it is important to inspect and replace these items when necessary.

  • Q:

    How does a brake servo work?

    A:

    A brake servo, also known as a brake or vacuum booster, works by creating a partial vacuum within, which then increases the force applied to the main cylinder. With a brake servo, the brake pedal first presses an attached rod, which then allows air to enter the booster while closing the vacuum. Pressure then increases on the rod that connects to a rod inside the master cylinder.

  • Q:

    What is a traction control system?

    A:

    Traction control is a system designed to prevent automobile tires from losing traction due to differing road conditions by adjusting the amount of braking applied to each wheel. If the system detects one tire spinning faster than the other, indicating a loss of traction, it can redirect power as needed.
