a couple days ago i put in some 3" spindles and had to grind down a little portion of the lca. since i put these in about 5 days ago, there is a weird rubbing/grinding noise that only happens when i apply the brake at low speeds (if I'm going 45 and start to brake, the rubbing/grinding starts at around 5-10 mph). it also doesn't happen every time i use the brake or when the steering wheel is turned. when it does happen though it tends to pull to the right, which is making me think it has something to do with that brake caliber or disc. i thought it would go away but it hasn't and i might have even gotten worse. any ideas of what this could be?

 

nothing?

 

I've heard issues of the calipers hitting the old bump stops causing the caliper to not grab, but never what you're describing

 

Check your bolts that hold the caliper bracket onto the spindle. They have a tendency to walk out and have even cut a wheel in half (member posted pics) if that's it use locktite

 

thats what i was thinking. thanks

 

i finally got around to checking it and everything seems fine. now I'm thinking it could have to do with the brake lines or something

 

This happened to me. One bolt walked out completely, the other was close. Caliper ground up the backside of a brand new rotor. Came home and pretty much poured Loctite on the caliper bracket bolts.

Also check your caliper slide pins. Regrease them while you're in there.

 

alright thanks i'll definitely check this out

 

i checked everything and turns out the disc brake is warped...
