Default Remove and replace brake master cylinder

For this you can replace your master cylinder with a new/rebuilt unit, or remove yours and rebuild it,

Make sure you cover your fender to prevent scratches or brake fluid dripping on your paint.

Locate your master cylinder. It'* on the drivers side fire wall.


First thing you will need to do is unplug the fluid level sensor. Pull on the plug, not the wires.


You will need a small pan or cup to catch your brake fluid. Do not reuse this fluid. Only use new fluid to refill the reservoir. Remove these two brake lines and allow reservoir to drain in to pan. Cover tube ends to prevent debris from entering the brake system.


Now, there are two bolts holding the master cylinder to the brake booster. You will need a 15mm wrench to remove these. One on each side.

Here is the other.


Now, simply slide the master cylinder out.

Rebuild your master cylinder or use a new/rebuilt one

Install master cylinder in the reverse order as it was removed. Torque bolts holding master cylinder to brake booster to 20 ft lbs.

Install brake lines and torque to 11 ft lbs.

Plug in brake fluid level sensor.

Fill reservoir to the full line.

You will need to bleed all 4 brake calipers to ensure ALL air is out of the brake lines.

Press brake peddle with your foot. It should feel firm and not fade. Hold peddle down, it should stay in place. If not, bleed the brakes some more.

Check the
reservoir several times while bleeding. Keep it full.
