List of parts you will need:
- Rebuild kit ~$30 from Toyota (Part # 04479-17011)
- Various sockets and pliers
- Denatured Alcohol
- Brake Fluid
- To do a complete rebuild you will also need:
- Snap ring pliers - long and skinny set (Craftsmen #30353 work well)
- SST #09756-00010 ($4 from OTC)
Here's the SST that you need if you want to do the full rebuild on the rear
1) Remove caliper from vehicle. Skip to step #4 if you left the
mounting bracket on the rotor.
2) Remove 12mm slider bolt.
3) Pivot the caliper mounting bracket and remove it from the caliper.
Here's the caliper, and check out that ratty piston boot!
4) Remove the main pin boot with a screwdriver. It may take a
hammer to urge it off.
5) Remove the sliding bushing and boot.
6) Peel the cylinder boot down off the piston groove.
7) Using a pair of need nose pliers turn the piston counter-clockwise
out of the cylinder.
Just a pic of the piston removed.
8) Remove the cylinder set ring with a screwdriver. You may need
to dig around a little to find it. Then remove the cylinder boot.
9) Insert the SST onto the adjusting bolt, and lightly tighten
it with a 14mm deepwell socket.
10) You should be able to see the snap ring down inside the cylinder.
Take a set of long, skinny snap ring pliers and remove the snap ring.
I used a Craftsmen #30353 and was able to remove it the first
11) Pull out the SST, spring retainer, spring, spring plate, and
stopper together with the adjusting bolt. May take some wiggling with a pair
Here's the empty cylinder.
12) Onto the parking brake. Remove the 14mm bolt and cable support
13) Remove the torsion spring with a screwdriver or pair of pliers.
Remove the 17mm bolt from the parking brake crank.
Not a necessary step, but if you want, remove the crank bracket
from the crank. A 2 jaw puller may be necessary.
Pull out the crank.
14) With a screwdriver remove the parking brake crank boot. A
hammer may be needed to urge it off.
The empty crank cylinder.
15) Another unnecessary step, but you can remove the stopper pin,
that holds the torsion spring in place. A set of pullers or a pin punch works.
Here's all the parts removed.
And here's the dissambled adjusting bolt. Pull off the tiny o-ring
on the head of the adjustment bolt.
Clean up all reusable parts with new brake fluid or denatured
