i just noticed it today, its been raining up here decently. i never slam on my brakes, or hardly every. its a decently loud clunking coming from the passenger tire area. i havent had a chance to take the tire off and look given its pouring out, the brake pad should be fine i checked it when i did my oil 3 months ago and they were about 60%.

any ideas of what i should check into first, also all grease points have been greased during the last oil change

thanks in advanced!

 

also no pulsating peddle or rough ride. drives pretty smooth. I will take the wheel off tomorrow, what should i look for?

 

Make sure the caliper is bolted up tight to begin with. Once you get it off take a good look at the pads and rotor. Look for uneven wear on the pads and/or a warped rotor. You may not be able to tell with the eye if the rotor is warped so a dial indicator could be very helpful.

 

Check the bolts and bushings for the calipers too. if they are worn, or missing it could cause this problem.

 

the lower bushing looks stuck shut, unlike the top part where you can see both grooves, this is pushed together, will upload pics so i can confirm this

 

i found the part number, 5470497. local dealer says this part is discontinued, but may still be able to order them. found them cheaper on ebay from a gm dealer, i should just replace both or just the broken one?

 

I cant post the third pic. idk why. when i took the caliper off, a decent amount of rust came off with it, but nothing looked damaged

 

this may also sound dumb, do you think I should grease the pin? it still looked shiny and lightly slippery. if so what grease would you recommend

 

pins and boots are common replacement parts. I use Sil-Glyde brake lubricant.

 

will have to pick up some sil-glyde, thank you! you just apply a light amount from what i was told right?
