Best Brake Upgrade on the market?

Needing to upgrade the brakes on the CJ8 and it has disc in the front and drum in the rear. What is the best brake kit that will make this Jeep stop better?
 
I've got ECGS axles on my 8 and I'm really happy with them all round. The brakes they use are impressive: chevy 2500 discs up front and Ford explorer discs in the back with internal parking brake drums. She stops like a modern car now.
 
Wow, 2500 series rotors are massive compared to stock CJ rotors.

Install a duel diaphragm booster and matching master cylinder. It will make a significant difference in your braking. I used the Navaho system from Off Again Off Road. There are others.

John, I am thinking I need to add more stopping power now that I am on 35s. I have heard about hydro assist, but was leaning toward just a dual diaphragm set up. I suppose you are happy with your set up?

I’m quite satisfied with what I have, it stops well, even in 4:1 low range with the automatic. Hydro boost is more stopping power and a bit more involved to install, but it will put your nose on the windshield in a heartbeat.
 
Hello: OK, I'm having problems to stop CJs with 33" and larger tires... At this moment I want to improve the front brakes, replacing the stock calipers with ones with 4 pistons in place of 1... Larger pads with adequate presure and I think this will be a good stuff....

I Will start with a pair of calipers from an old 1967 Mustang... because I have it!! And the thickness of stock Mustang's rotor is near the same of our CJs.

At the moment I do it, will post some pics....
 
Focus on the master not the wheels. The calipers can only do with the volume and pressure the master gives them. Here is the list of parts that I've used:

YJ bracket booster bracket

1988 S10 9" dual diaphragm brake booster

1980 FSJ 1-1/8" master cylinder (with disc/drum)

PRE7486 - Universal Pedal Rod Extension

Cut the S10 boosters end off and thread it to 3/8"-24 (the common industry standard). The PRE7486 has a female end with that thread already. You will have to swap the lines on the FSJ master as compared to the stock CJ unit. The YJ bracket will need the bolt pattern on one side slightly enlarged, but the firewall side is the same. This is the basic formula that Vanco sold years ago. If you have a disc/disc set use a corvette master from the last seventies that is 1-1/8".
 
OK, I think will take the 9" power booster, because I have hidraulyc clutch and don't know if the S-10 booster with YJ bracket could not have enought room.... We have rear discs and the Corvette pump was the choice at first time...
Thank you very much....

I ended up going with a 9” dual diaphragm set up (A-team performance) and I am very happy. The Scrambler is on 35” tires and the pedal feel is so much better and so much more reactive.

Isn't the A-Team Performance an 8" booster? Still a nice setup.

Same amount of room for a hydraulic clutch master cylinder on the YJ bracket as the CJ bracket. A lot more YJ's had factory hydraulic clutches over CJ's.
 
OK, would you recomend where to buy the YJ booster bracket?? please.... It's the only part that I can't find....

Mine is a Vanco unit that I put in to go with the Cherokee 44/Grand Waggy HD20 and I've been happy with that setup on 35s. Good enough to drive all over the damn country :crazy:
