Tacoma rear brake disc conversion

Don't do it. Seriously, do not do it. Use the search button and you'll find the reasons why.

 

Rear discs, calipers, installation, new master cylinder, proportioning valve and time spent tuning it, etc. Disc brakes require less pressure but more volume than drum brakes, so you're looking at swapping out the full system.

I converted to rear discs almost 2 years ago and I'm still not done with the project. At this point I've scrapped the entire ABS system, plumbed new steel brake lines, am running manual brakes, and am on my 3rd master cylinder.

None of that addresses the caliper clearance issues that'll come up. My calipers are mounted behind the rotor and nearly wore a hole through my rear shock from rubbing during articulation. Expect to have to fabricate custom shock mounts both on the frame and on the axle to make sure nothing rubs.

I still have worse braking performance than I did with the rear drums and the parking brake has trouble holding the truck in place.


Get yourself some SP Performance slotted rotors and Hawk pads from RaceShopper.com, some stainless steel braided lines from All Pro, install them and call it a day. That'll firm up the pedal and knock about 20 feet off the 60-0 stopping distance.
