low speed brake grinding/pulsating problem! by ajrock2000

1998 Jeep Cherokee 6 cyl 4x4 Automatic
 
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...

It is most likely that you have set the booster output pushrod too long.
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

airock2000 did you ever find the answer to your problem because I have the exact same issue and it is driving me crazy trying to find an answer.

Yes, I did! I had recently replaced the u-joints in the front wheels and part of the spindle got broken a bit with the hammer, so when it was spinning the abs sensor was not picking up the correct reading, so at low speeds it caused the abs to kick in and go haywire. What I did was disconnect the abs sensor in the front wheel and it turned the abs off, now my brakes work fine.

2004 Grand Cherokee Limited Brake Questions by trailrated39

Hi all!
 
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
James

This is probably as good a place as any. People tend to follow exisiting discussions and may not see a brand new one anyway, especially if it seems to be a "duplicate".

Hi James,
      
     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.
