1st Brake Job... Sounds like a Choo Choo

Hey Everyone,
I did my first solo brake job on the back end after the driver side caliper stuck and.... Well, there wasn't much left.

So, 1 driver side caliper, 2 new rotors, and a set of pads later, I bled her, buttoned it up and took it for a test drive. Something on the PASSENGER side is making a "shoosh shoosh shoosh" sound. It's definitely once (1x) per revolution. That makes no sense to me!!!!!!!!!!!!!! If it was b/c I hit the dust shield trying to get the stuck rotor off, wouldn't the scraping (or "shooshing") be constant? Did I get rotor that's out of whack?

Please help, I've gotta get out of the garage and do ANYTHING else. I'm actually thinking about cutting grass to get a break from this crap.

Does everything feel ok? Maybe the other caliper froze?

It feels ok... I guess. I took the caliper off and put it back on with no problems. Didn't have to push the piston in or anything. with the tire off and tranny in neutral, I can turn the rotor. Can't figure out why it's not a constant sound, why it's only once per revolution???

Look at the boots around the pistons in the caliper... are they torn or otherwise compromised? Those need to be weather-tight. If water gets in there it'll rust and freeze up the piston. If all still looks good I wouldn't worry too much about it and drive for a while to see if it gets better or worse.

The boots are ok... and slides were re-greased. I'm thinking the outer edge of the 200+ rotor is a little out of round, and hitting the the inside of the caliper.

Could be. Thought you replaced 2 rotors tho? Noise coming from front or rear?

Did you have the rotors turned, you might have a warped rotor.

Pulled the problem rotor (passenger rear) and took it back to parts store. Turns out the inside diameter of the rotor was machined wrong. Looking straight down on it, one side was visibly wider than the other, which made it oblong. Only I would get a part made wrong from the factory...

I won't have the new rotor until lunch time tomorrow. I've got stuff to do and I'm going crazy!!!!!!!!!!!!!!!!!!!!!! Thats life... Guess I've got to ride my bike to the beer store.

Thanks for the help!

Make sure they true the rotor up at the parts store before you leave.
