All,
I just put on new pads and rotors on my wife's toyota matrix.
Simple process.
Received powerstop pads, and autospecialty rotors from rock auto as part of a kit. First rotors had deep grooves in them, from machining error. They went back, and rock auto replaced.
So, I dug into the job.
Car was from Buffalo, NY so it was fun and rusty to work on.
On the one side, both caliper boots were ripped, and had no grease. I greased up the sliders and pins, and put everything back together with new boots (AC Delco brand). Also did new clips.
Everything seemed right, but one caliper pin was a little scored and black. The rest of the caliper pins were shiny metal.
So, it was getting late at night, so I just put grease in it, and cleaned the black one up with sandpaper to smooth it out.
So, I did the proper rotor bedding as per powerstop instructions, to spread the friction material evenly on the rotor.
So, now I am noticing a loud roar or rumble when I get on the brakes from a high speed, and slow down. There is no pulse, there is no squeek, just a roaring sound.
Is this a stuck caliper pin?
I was thinking of going to carquest and buying 4 pins, and replacing them all, and a big tube of brake lube, and relubing the pins.
Those envelopes of brake lube really aren't enough to grease pins and contact points, and I like to lube the back of pads as well.
Thanks guys!
Justin
