Well I didn't have much brake pressure when I first got the jeep. Its a 1990, so I went to bleed the breaks and couldnt get the nut around the valve loose. I said screw it and put the tire back on and then had no brakes. Ive heard the 90's had some break problems so im curious if theres anything else you guys think may be wrong?

When was the last brake system service performed on this gallant steed?

Crayfish03

ha... not sure. The book has a list of services that was done and the last one the guy wrote down was in 2013.

Wouldn't be an entirely bad idea to get it up on jack stands remove all four wheels and have a look. If it's rotted or worn toss it & replace,
no brakes = bad news.

It was bad news this evening when I went to back it out of my drive way. haha. Rolled out into the street. Glad there were no cars coming.

What is this refering to? Front or rear? What condition overall is the Jeep? Rust issues??

Do a good inspection looking for leaks in lines. Seeing that most don't have 4 jack stands, do one axle at time, for repairs. Some PB Blaster or such, and a bit of heat might be needed.

Does it have the dreaded ABS?

Crayfish03

Cruiser im not sure what dreaded abs means sorry. And It was the front. We got them off and bought new valves on both fronts. Finished bleeding them and still didn't make a difference. Planning on inspecting the rear tomorrow. And yes it does have quite a bit of rust.

What "valve"?

Larry's XJ

If you somehow let the master cyl run dry, then you have to bleed that first. Then you move on to wheel cyl/caliper. As they say on here, some "Noggin Pokin" looking for any leaks in the hard lines, wheel cyls, portioning valve, calis, even around master cyl.

Only "valve" that I know of would be the Proportioning/ brake bias valve. (front/back)

Someone help this caveman out with proper spelling/terminoligy for the "bias valve"

I just assumed he was referring to the bleeder screw. (Also assumed he didn't know anything about brakes). There's been no brake issues on the '90 that I'm aware of.

Crayfish03

haha nope don't know a damn thing about brakes. And yes bleeder screw. Either way replaced it and got the front brakes bleed and it didn't do the job.

What we have here is Failure to comunicate

"Didn't do the job"
What the smurf is this supposed to mean?

Really need to explain the problem a little clearer/more detail.

What is doing, or not doing?
