New pads and rotors, rear brakes grinding now

[Dustin Jackson]

how in gods name could you replace the rotors and not see the parking brake assemblies you installed the new ones over?...

@bladenbullet There are many parts of this vehicle that I do not know about yet and slowly but surely I will familiarize myself as I do my own work. I was replacing rotors and pads, since the parking brake assembly is independent from the rest of the brake system there was no reason to have an education on it.

First mistake was buying from Detroit they peddle Junk! Sorry I found out the hard way! Had to replace entire front end!

The pads are the same for the inside and outside so all I can think of is if you put them inside out as in metal to metal but I’m not sure if that’s even possible.

A buddy of mine did that once! I was showing him how to do his brakes... this was in our teens. I did one side, he did the other and he put the inside pad on backwards.

The parking brake doesn't do anything to the pistons, it actuates the shoes on the hat portion of the rotors out back. They need to be adjusted, especially if you replace the rotors and there is a process that must be followed for them to work right afterwards.

I replaced my rear rotors/pads before and didnt have to do anything with the parking brake that I recall. Parking brake and pads work fine over 20k miles later.

What was the problem? Were they grinding?

@Dustin Jackson have you figured this out yet? Are they still grinding? How about a picture of your rear rotors please.

wouldnt any type of rubbing or grinding be related to bolts being too loose causing vibration or the calipers sticking? I would first try to find which wheel is rubbing (maybe both). You can tell through how much heat is felt in the brake area. Compare to other wheels after a descent amount of driving. Make sure the pins are cleaned. Did you feel any issues pushing the piston back? If they give you a lot of trouble, could be potential issues. Also make sure Ebrake is not on when you are trying to change brakes.

@Rocket Man @Meccanoble I have not had a chance to look at them yet, I'm about 2000 miles with these brakes and they work fine 50% of the time.

I just did a replacement of the rears pads/rotors on my 2017. I had the drivers side parking brake hanging up and ended up replacing those as well. But as previously mentioned, check the parking brake system. The reason I say this is the pins which hold the shoes to the facing sometimes get twisted and release the shoe. That is what I think happened and caused my issue with the drivers side. I would hear some noise out of the rear hub but not all the time.

Just a suggestion. Hope you get it solved ASAP, nothing good about grinding noises coming from a hub.

It only takes a few minutes to pull a wheel and caliper to see what’s going on. If your pads are grinding marks or grooves into your rotors and you’ve driven 2000 miles that way, they’re toast and could be dangerous. Saying your brakes work fine 50% of the time sounds kinda crazy don’t you think?
