Front Caliper Rebuld Page 1/2

I'll try to go about explaining the caliper rebuilds. However,
this was during my suspension rebuild, so some of the pics may look
- Various sockets and wrenches
- Rebuild kit ~$20(Toyota part # 04479-32011)
- Air compressor (to remove caliper piston)
- Denatured alcohol or brake fluid to clean parts
Here's the front rebuild kit, about $15 from local auto parts
1) Loosen lugnuts, raise and support front of vehicle. Remove
lugnuts and wheel.
2) Drain the brake fluid pressure from the bleed valve on the
caliper. Place a hose over the valve and use an 8mm wrench to loosen the valve.
3) Remove the two 12mm bolts that hold the caliper to it's mounting
4) Remove the 14mm banjo bolt holding the brake line to the caliper.
Expect some brake fluid to leak through.
5) Here's some pics of the caliper removed.
6) Push the slider out one side of the caliepr. I just used a
pair of pliers as shown below to do this.
7) It should pop loose, then you can pull it the rest of the way
8) Remove the 2 rubber dust boots.
9) Inside the caliper, you will see a collar. Remove this.
10) Do the same for the other sliders, and here's the parts you
will have removed.
11) Use a small screwdriver to pry out the piston set ring.
12) Pull out the piston boot.
13) Remove the piston from the cylinder with compressed air connected
to the banjo bolt hole. Tighten the bleeder valve and make sure to place a block
of wood or a rag inside the caliper, so that when the piston pops out it is
not damaged. And believe me it will POP.
14) Pry out the piston o-ring with a small screwdriver. Be careful
not to score the cylinder walls.
15) Just a pic of the cleaned up calipers after under a brass
16) Clean the sliders and collars in denatured alcohol or clean
17) Also, clean the inside of the cylinder and the piston with
denatured alcohol or brake fluid.
