Brake Pad and Rotor Replacement - Front RWD

Step 65 - After servicing the caliper slide bolts, install and tighten bolts onto the caliper.


Tighten Caliper Mounting Bolts

Step 66 - Once the caliper is installed, mount the brake line onto the caliper and tighten securely. (Note: Copper sealing washers needed for this step.)


Securely Tighten Brake Line

Step 67 - Next, remove the dust cap that covers the bleeder valve. With a helper holding down on the brake pedal, slowly open the bleeder to allow brake fluid and air to escape. Once the brake fluid flow stops close the bleeder completely. Then have the helper slowly allow the pedal to return to its normal position. (Note: Check brake fluid levels, before and after this operation.) Reinstall dust cap and wipe clean using a shop towel. Repeat these steps for the opposite side, always perform this repair on one side at a time to avoid confusion. Reinstall tires and lug nuts to tighten.


Bleed Brakes

Step 69 - Using a shop towel, clean the brake master cylinder reservoir, remove the lid so fluid can be added.


Remove Brake Master Cylinder Lid

Step 70 - From a sealed container add brake fluid until the level meets the "FULL" line on the reservoir.


Adding Brake Fluid

Step 71 - Once the fluid has been installed to its proper level, reinstall the lid and wipe an excess brake fluid with a shop towel.


Reinstall Brake Master Cap

Step 72 - Next, slowly push the brake pedal down, then slowly allow it to return to normal position, repeat this action until normal brake pedal operation returns. (Note: Never operate a vehicle without normal brake pedal operation.)


Push Brake Pedal Down

Once the repair job is complete, drive the vehicle gently as the brake pads wear in. Once a few blocks of stop and start driving occurs the brake pads in be properly set to the brake rotor. When first driving the car after any brake service listen for "out of the ordinary" noises. If irregular noises are observed stop operating the vehicle and repair as necessary.

Each serviceable wheel bearing front brake design has minor differences but all share the same principal.

Helpful Information

Brake pads and rotors are normal service items on every vehicle. If the brake master cylinder is low on fluid or a squeaking noise is observed the brake pads should be inspected. This condition can be accompanied by a brake warning light on the dash. There are major differences between front wheel drive brake jobs, and rear wheel drive front brake jobs because of the location of the drive wheels.

Most replacement brake rotors with bearing hubs built together will have new axle bearing races already installed. Some safety precautions include never using compressed air to clean brake parts because of hazardous materials.

Best Practices

  • Bleed the system after brake job is complete.
  • Slide the tires under the vehicle for added safety while carefully avoiding jack stands.
  • Always perform brake replacements on one wheel at a time to avoid confusion.
  • It is a good practice to bleed the brake system when replacing brake components.
