My 2004 WJ’s brakes are still making a lot of noise. At the same time, I changed all of the pads and the front and rear rotors. Wagner thermoquiets are what I used, and I have never had any issues with them. I greased the metal almost entirely and the pads on all corners. While I’m there, I was planning to check the brakes and install my Kor lift Tom. I am not sure if I missed any locations or if there were some that didn’t get greased. So should I check anything else in addition to changing the pads and the bolts again? Would bleeding the brakes also be beneficial? How difficult is it to achieve this? What kind of brake grease is required?
If your brakes are still squealing after replacing the pads and rotors, check for dust trapped between the rotor and caliper. Mechanics usually use brake cleaner to clear out any debris during installation to prevent noise. Also, make sure all hardware like clips and caliper pins are snug. Bleeding the brakes might help if air got in. It’s not too hard to do, and using high-temp brake grease is key for smooth braking.
When I faced persistent brake noise issues with my 2006 Jeep Grand Cherokee, I did a comprehensive brake job similar to what you’ve described—replacing pads and rotors with quality parts and thoroughly greasing the necessary components. However, the noise persisted. I found that ensuring all contact points between the brake pads and caliper brackets were well-greased and free of debris was crucial. Bleeding the brakes can also help eliminate air bubbles that might cause sponginess or noise, especially if the brake fluid is old or contaminated.
Bleeding brakes can be moderately challenging if you’re unfamiliar, but there are plenty of online tutorials and guides to assist. Use a high-temperature brake grease suitable for your vehicle to prevent noise and ensure smooth operation of the brakes. It’s a meticulous process, but addressing these steps thoroughly should help resolve the noise issue effectively.
