Said It Here

Brake parts missing or falling off after service

Mechanics occasionally leave behind loose hardware like slide pin bolts and clip wires, which can fly off while driving and cause strange noises like trilling against the rims. Missing components leave drivers wondering if their vehicle is safe to drive at high speeds or if they should wait for replacement parts.

“I now know that the 'trilling' I heard when I picked it up from the shop/drove to work yesterday is from the silver wire that's clipped in hitting my rims, due to the one on my right wheel flying off today and the noise stopping on that side.”source ↗

“I did that once. Fortinately nothing happened. Went to the junkyard, got a new bolt, and torqued to spec”source ↗

“And damn if the locking bolt for one of the slide pins isn't missing! The bolt for the bottom slide pin is there, but the top one is not. Now I'm wondering if it's okay for me to drive the vehicle without that bolt, or whether I should wait until a replacement bolt comes in?”source ↗
