Alot have said that in hard breaking without prop valve the rear backs lock up. With the prop valve they don't, they supply actual braking vs just dragging tires! Almost everyone has said with the prop valve they can stop harder & quicker than without it. You choose though, cause everyones different.
Do the swap & keep your normal prop..then swap props and see which you like better. It takes like 3 minutes to swap em, so its and easy switch and the prop would only cost like 5 bucks at a junkyard.
This is exactly what I'm doing cause Idk which is better honestly..too many opinions.

Can u take the master cylinder index just bolt that on instead of switching the prop

Kamaran

I haven't seen anyone do it but you shouldn't have an issue either! Its jsut alot easier to unscrew the prop and do that lol.
I got a 99-2000 brake booster for the dual diaphram upgrade, and as far as I can tell the master looks the same as my 88 with the exception of how the hardlines are bent. Looks the same as the ZJ's in the yards as well! I thought I would need the whole master as well but it isn't nessesary, just the prop valve!

I have heard of people using masters off of old dodges and some others to get more stopping power. Most of the time, the pedal is sup sup stiff but they do stop alot better! Search google for master cyl upgrade, if your gonna switch it you may as well upgrade right? If not the prop will do just fine!

I just don't like the look of the old style ones

Kamaran

Of the actual brake booster? Got a pic of what your actually talking about?

This is what I got I wont the clear one

Kamaran

Perfect lol. Mine lookes like that..its an 88.
This is the 99-00 version I picked up.


What year is your jeep?
You can get the later XJ on or a WJ one. If you don't have any if your yards, I think we have a WJ in our yard currently..if you want I can pull the brake booster from it and ship it to you for whatever they want for it + shipping. No charge other than that! Plus people perfer the WJ version I guess cause its about 1" skinnier than the cherokee versions..gives more room and a cleaner look I guess!
I also wanted the clear! I think it makes the engine bay much nicer!

I have a 94 Cherokee and that is what Im looking for let me check my pic-a-part and ill let u know, how much would it be from u?

Kamaran

I would charge you whatever the junkyard wants + shipping cost..no charge for labor or anything. They only take 10-15 minutes to pull unless you wanna give me the 2bucks it cost to get in
I like going to the yards and poking around often..good way to find cheap upgrades lol.
And yours being a 94, your brakes will be better with this upgrade! Its called the dual diaphram brake booster upgrade! You and everyone else thats a 94 or 95? down has a single disphram version..96+ got dual setup I believe!
So looks and a braking upgrade! Bam can't beat that!

Ok thanks I will check my pic-a-part and ill let u know

I want rear discs!! These drums are killing me. Plus it makes maintenance super easy after it's all in and working properly.

I have an 89 XJ D35 non C clip. I have access to a complete 2004 Crown Vic's rear disc brakes all for only $100.

I know the early to mid 90's are a near bolt on conversion but will this '04 work? Has anybody done a similar conversion or know the difference between 90s and mid 00s rear disc brakes?

majastee508

Anyone done this swap and dealt with the abs?

cherokee104

I have a dana 35 on my 00 jeep cherokee with abs and want to do the rear disc brake conversion. Does anybody know what exactly is needed to do the conversion with ease and does any body have a kit available?
