Parking shake

Ive got a stock 85 XJ 4x4 and i recently did a break job of both front rotors and pads( while i was changing the two front axle u joints that were busted and also put new hubs on it cause they were pretty banged up from trying to get them off). After the change the brakes seem real squishy and almost non existent. I think i have a slightly hung up caliper cause on the highway if you go to stop it will try and pull right, unless its the MC.

Also if your turning left into a parking spot and hit the breaks ever so slightly they whole front end of the Jeep shudders and feels like my break are binding up.

Any suggestions on what it might be?

If I were you, and if you are planning on keeping it for a while, well regardless for safety reasons, I would replace the calipers. They are relativly inexpensive and will most likely solve your problem. The same situation happened with mine, a seal or something got ruined in the piston when I pressed it back to get it on the rotor.

Replace calipers and bleed the lines thoroughly.

Grab some new hoses to go with those new calipers while your at it...


...but if you're cheap and broke like some/most of the people here, try lubing the caliper slide pins (or whatever they are called) and bleeding what you have first and see if that helps.

Good luck

Ill probably will get new calipers here in the soon near future but i cant help but think its the damn MC. Cause the pedal is acting real weird. Like right after i did the brakes you could go to stop and the pedal would go all the way to the floor and my brake light would pop on. Then after you starting going again either the light would go off or you would pump the brakes and they would get better eventually.

Freakin weird

If you pushed the pedal to the floor when you blead the breaks, you may have damaged some of the seals in the master cylinder. They get brittle and wear, and when you put the pedal down they can disinigrate. That may be your problem. However that still does not explain the pulling to one side when breaking, it just explains the poor pedal feel. I would still replace the calipers, since all of the other stuff is new. If replacing the calipers and rebleading the brakes does not fix the problem, then you know it is the master cylinder.

To others that read this, if I am incorrect in my thinking please correct me.

I totally agree. The MC shouldn't cause a difference in the pressure to either side, just the squishy feeling. The brake hoses can definitely make the car pull to one side. Like he said, you can damage the seals in the MC when you bleed the breaks. I usually put a brick or 2x4 under the pedal so it doesn't bottom out. When I changed the brake lines for my lift, I just cracked open the bleeders and let 'em run until the air was out. Takes a little longer, but still works. Sounds like you may end up replacing most of the brake components, but thank god for the aftermarket parts stores. You can't beat their prices.
