95 brake booster vs 93

Just want some reaffirmation. The 95 Yj has a dual diaphram booster, right? Will I notice a difference over a the booster in my 93? Thanks.

Only 95 YJ's with the 4.0L motor came with the dual diaphragm booster. The 4 cylinder Jeeps still had the single diaphragm boosters. You should notice a difference with the dual diaphragm booster. I have a 95 YJ dual diaphragm booster in my CJ and it will lock up my 37" tires. You will also need the firewall bracket and master cylinder from the 95 YJ. I would also try to get the lines that run from the MC to the proportioning valve because the master cylinder takes metric thread fittings and the brake lines need to have a bubble flare on the end of them. A single flared line will also work if need be.

I've been in this rut plenty long enough, I know what to expect. Weather my day is hell, or weather it goes well is kind of up to me I guess.

^ Don't listen to CjinPA. He doesn't know what he's talking about.


Just kidding. Considering he gave me one of the 95's.

94 YJ w/ stuff. All the work/money I put into it, and the comment I get most is my $20 mod: "Hand throttle?!? That's awesome."

I agree with everything said above. It ranks up their with the fuel injection as one of my favorite mods. It is nice to only have to barely touch my brake pedal to come to a quick stop.

Just like CJinPA said you will need the 95 master cylinder as well and I also used the 95 brake lines to prop valve due to the 95 master having metric threads.

Your funny Ross. If your never going to put the 95 dual diaphragm brake booster that I sold you in your Jeep maybe this could be a potential sale for you.

As for the difference between the single diaphragm and dual diaphragm set ups, The single diaphragm brake booster puts out somewhere around 1000 lbs of pressure. The dual diaphragm booster puts out around 1500 lbs of pressure so you get 50% more power to your brakes.

Well I bought it off you before I did the 8.8 swap thinking I might need/want it. But the rear discs gave me a lot of extra stopping power. I'm still going to swap yours eventually.... probably some lazy rainy day this summer.
