Causes and How to Fix Grinding Noise After Replacing New Sintered Brake Pads

There are a few reasons for grinding noise after replacing new sintered brake pads.

1. The sintered pads are new.

When your brake pads are new they need a little bit of wearing in so they can function normally. This is commonly referred to as bedding in. It's kind of like getting a new pair of sneakers, at first they are a little bit uncomfortable, but with constant wearing in the next few days they loosen up.

2. Rust or debris.

If there was some dirt or rust on the rotors while you changed the pads, the pads might be grinding because of that, so in that case you should change the rotors, have them machined, or better yet, take your motorcycle to a mechanic.

3. The calipers were not positioned correctly while changing the pads.

In this case the caliper can drag itself on the rotor causing a grinding noise and damaging itself. In this case you should remove your wheels (first the front, then the back) and feel the entire brake assembly to see if anything feels loose. If it feels solid, spin the rotor (with the wheel still off) and listen to it. If there isn't any noise, repeat that with the remaining wheels to track down the caliper at fault.

4. The shims are not lubed enough.

If there's not enough lube between the shim and the caliper, the brake will make a whine or a squeak sound (maybe sometimes even a grinding sound). You can resolve this matter with applying a bit of silicone lube between the shim and the caliper.

5. The rotors are worn.

If you install new pads on worn rotors they will make a grinding noise because the new pads need a smooth surface to rub against or otherwise it will come to shortening the life of your brake pads. This is resolved with buying new rotors.

How To Replace the 2006-2011 Chevy HHR Control Arm

Due to a worn out rear lower control arm bushing on the passengers side, and the drivers side one getting a wee bit sloppy, I replaced both lower control arms. The local dealer wanted $495 to replace just the rear bushings alone (yea Canada), but I picked up a pair of chevy hhr lower control arms , complete with all bushings and the lower ball joint installed, from HexAutoParts in the US for $59 plus taxes.  NOTE: If you are shopping for replacement Lower Control Arms you may find stamped steel ones being offered for the HHR - those may fit, but are actually for the Cobalt cars. The HHR's use cast ones, not stamped steel - the cast ones are definately recommended. Here is the process used along with a list of the tools used, as well the torque specs, and a few tips on the process: Tools:  - 15 mm socket  - 15 mm box end wrench - 16 mm socket - 13/16" socket - 6 inch extensions for the sockets - torque wrench - small pry bar - screwdriver - small
