here is an odd thing to ask.

my brakes are spongy. always have been since i bought this cherokee. i replaced all the parts but the proportioning valve since i was told that if it let you have brakes when your line snapped, it was working. and it did, when the rear line broke, the proportioning valve locked off the rear line, just like i hear its supposed to do so i could still stop with the front brakes. a buddy of mine is working on a cherokee with the identical problem, squishy brakes. he power bleed them on a machine, did htem the old fashioned way, everything, just like i did and he is still having hte same problem. he did some googling and came up with removing a seal in the proportioning valve and it should stop the spongyness.

what do you guys think? i have been driving with the brakes feeling terrible for about 6 months and i get really nervous in stop and go traffic because of how they feel. i have replaced it all but the booster and proportioning valve because they tested good. what do you guys think about this seal in the proportioning valve being removed? you ever hear of this to fix the problem? anyone else have this problem and figure it out?

i gave up trying to fix it but since this new idea popped up, i am back in the game to fix the brakes

 

No ideas guys?

 

Sounds like the valve is stuck. Dont know of any way to fix it, just have to replace it.

 

Well, no ideas, but I don't understand how anybody can drive a car for six months, or one single day for that matter, with spongy brakes? Seems totally and utterly unresponsible to me.

So my advice to your: STOP DRIVING AND GET IT FIXED OR HAVE IT FIXED!

How can you give up fixing your brakes and continue driving for six months with "the brakes feeling terrible" (your words) and getting nervous????

What if you crash into my kids crossing the road, because you've given up??

Are you nuts?

woah. dude i agree that's unsafe to do. but geez man chill

 

I've just re-read your posting after I posted my response. And I just can't believe what you're saying !

Here you are writing:

You call it an "odd thing to ask". Well, pardon my French but are you insane??? Please tell me I'm wrong and that you are a responsible adult who would never endanger anybody by taking a car with wonky brakes onto the road??

grab a dual diaphragm brake booster/master with new proportioning valve out of a 97+ xj.

best upgrade i've ever done.

 

this is the way i am headed. they are not so bad that they don't stop but coming from bmw braking, it scares me when i hit the brakes and the pedal travels so far before stopping the jeep. sometimes the tires can lock up, other times they do not.

and this is not a daily driver jeep. its a play truck that i drive the 1 mile to work every once in a while. and with the brakes feeling so odd, i leave a lot of room between me and other cars.

 

hey superj just wondering if u ever got ur brakes working right cause i got the same problem ive replaced everything the booster, master, calipers, wheel cylinders, spring kit for rear even swapped my prop valve for a used one and still no luck anyway please get back to me thanks

 

How about adjusting up the rear brake shoes?

 

yep done that too actually keep the adjuster in my glove box lol

 

ive even made the mistake of taking it too the shop and have them look at it also had it pressure bled but all that did was contaminate my brake lines

 

make sure the calipers are on the right sides. (bleeder above the brake line)

 

Nothing ever fixed it. After that one dude answering like a jackass, I figured I would leav them and then run into him and say ot was the brakes

Nah, I adjusted everything as well as it could get and they stopped it fine but I never got them feeling like the brakes in my old BMW or the wife's wrangler.

 

ha-ha yea i hear ya, yea mine all adjusted too as mush as they can get and yes i double checked the bleeders being on top lol heard of people doing that tho o well just gotta live with a spongy brake thanks for the reply o almost forgot somebody said there was a recall on the prop i looked around but couldnt find anything on it atleast for the 87 can anyone confirm this
