YJ Brake Upgrade

(1/2) > >>

kirksjeep:
Since us YJ guys never had an option for a D44, we have to upgrade to the ford 8.8 rear.  With the 8.8 you get disc brakes, which help a little at stopping the bigger tires, but the YJ single diaphram brake booster is a limiting factor.  There are few upgrades out there such at using parts for 70's fords or finding a set up out of a 95 (only year that works, very hard to find and expensive) master cylinder and  brake booster.  I came across the link below that uses a set up out of a TJ.  Now I just need to get one off of Ebay (average price $45).

Sinister Fab makes this for a TJ.  Maybe it could work on YJ's too?

"This is Made to Fit perfect onto the Power brake booster plunger to make the dodge 99-01 master cylinders work on your Jeep TJ to upgrade your brake system for one ton style calipers."

I just picked up a brake booster, master cylinder and proportioning valve from an 04 TJ on Ebay for $40 (and free shiping).   ;)
