Better Braking for TJ with 8.8 swap

#1
A couple years ago I swapped in an 8.8 with disc brakes and expected to get better braking but I think it actually got worse than stock. Anyone have suggestions on how to improve it?

Upgrade to a 00-01 Durango master cylinder. Its a bolt in swap that requires no remaking of lines or fabbing a push rod. I'm using one on my TJ with ford dual piston 1 ton front calipers with chevy 3/4 ton rear calipers with a stock proportioning valve and have great brakes.

Edit: Here is the part number off of parts mike's site http://www.partsmike.com/store/store.php?crn=199&rn=1631&action=show_detail

Also there is a lot of good info on pirate 4x4 from mrblaine on TJ braking.

Another point of note is remembering that a lot of braking force in relation to the size bore is the master is dependant on the booster. Putting a huge MC (ram 3500/E350) on a small booster (like the stock TJ) is not the way to go.

hmmm... I didnt think my brakes were that bad, but I may have to try that.

Did you reuse the reservoir or did you get the durango one with the reservoir

You either need to upgrade your master or replace your proportioning valve. The 8.8 brakes take more fluid than the 35 drums did. You need a way to get more fluid back there.

I bought a whole new master cylinder with resi. The resi is about the same height but is wider and holds a good amount more fluid. Only issue I ran into was the mounting bracket for my PSC power steering resi wouldn't fit. But it was nothing that about 5 minutes with some angle steel and the old welder didn't fix.

A master cylinder that originally came on a 4 wheel disk truck will make a big difference. When I did the disk 8.8 swap in my '92 explorer (originally drum) I used a '95 Explorer (first year of disk rear) master cylinder and it worked great.
