The brake caliper needs to be replaced, and both front calipers should be replaced at the same time. When replacing, be sure to install the caliper with the bleeder valve on the top side.
If the problem persists, there may be a clog in the brake line.
My Jeep is a 1998 Jeep Grand Cherokee Laredo.
I hear a hissing/whooshing sound as soon as I start it. The sound seems to be coming from the brake booster.
When I use the brakes at any time, the hissing/whooshing sound stops. But when I release the brake pedal, the sound starts again.
The braking system works well.
Any advice?
Sure would appreciate it.
brakes will still work but you will have a prob with valves and stuff as it allowes the fuel mixture to lean out where the vacuem line is hooked to the engine thus causing the temp to rise in that area of the engine poss causing internal damage
The chime was going off advising me that my coolant was low. Upon a further look, I found that the float had fallen off the float sensor in the plastic tank, I fixed it and put it back on. Unfortunately the screen and chime kept saying the coolant was low, so I finally went to jeep and bought a new sensor and seal for the coolant tank. After installing it, I had not gone fifteen minutes and the chime and the screen advised me that the coolant was low.
Help!!!!!!
is running. With the engine off pedal is normal.

Sounds like there is either air in the lines or a problem with the power booster. This happened to me when I didn't pay attention and installed new front brake calipers on the wrong sides, which put the bleed valve at the bottom instead of the top (allowing air to remain in the calipers.)
I just replaced the front u-joints, rotors, and pads on it. However after test driving the jeep, a horrible clunking/griding noise comes from what sounds like the front left side of the jeep at LOW speeds. Applying the brake at 35mph+ renders nothing at all, just at low speeds. It is very loud and annoying, you can feel it right in the pedal. Any ideas? I double checked the pads/rotors and everything looks fine. I am guessing it has something to do with ABS? I need help! Thanks...
This rod should almost never be adjusted. The tolerance on the rod length is ± 0.007"
With the rod too long you are keeping the ports in the master cylinder closed and pressure is building up in the system and probably dragging the brakes.
Back off the length of the rod until you are sure you are not trapping any pressure in the system. This has to be checked with vacuum in the booster and the system at normal operating temperatures.
hope this helps
I've got a 2004 Grand Cherokee (Limited, 4.7V8, etc) that is coming up on 150K and is in need of some new brake components once again. Rather than go to the shop and get bent over like usual, I'm going to just tackle this one myself. I've done it before, so that's not the issue. My problem is that I don't know what pads and rotors to go with.
Now, I'm not looking to cheap out here. I'd like to get some pads that offer good performance for towing. I pull a 12 foot open trailer for both work and play, with loads ranging from a couple motocross bikes to 2000 pound of various raw materials. So towing performance is mandatory.
Conversely, this Jeep- despite being dearly loved- has seen a hard life of work, play and roadtrips, and wil probably be lucky to see 200k, so I don't want to get anything too expensive. Just something to last me the life of the vehicle.
Thanks

I just finished my brake job this afternoon. I went with the ceramic pads from auto zone. They all had a life time warranty. so I went with the cheep ones. I found out during my pizza delivery days that the metallic pads did last longer but the rotors didn't last as long. If you need to take the rotors off, good luck!. You need to get the retaining clip off the stud the get the biggest hammer you have and beat the hell out of it to loosen it off the hub. use a piece of wood to protect the rotor.
try to find the side that makes noise then then jack up that side and turn wheel to see or feel roughness as you turn the wheel
I just put new calipers,pads and rotors. We bled brakes. Could this be the brake booster ? How hard is it to replace?
took mine out and drove jeep had bad cvjoint at lower end and that was the problem
Thanks
