OSF brake squeak after new pads/disc/seal-kit

[Lewis Watson]

Hello all. I'm looking for some advice...

I got my car back from the garage today. One of the things I had them fix was a squeaking noise from the OSF brake while cruising at ~30mph. The noise went away when I applied the brakes. The garage reckoned that the piston had stuck, resulting in the disk getting warped. So they replaced both front disks, pads and fitted a new seal kit (all OEM parts)

Unfortunately the noise came back during the drive home, and now the garage is closed for the weekend. Could it just be the new pads still bedding in? Its odd that its the exact same side that is making the noise.

I jacked the car up so I could spin the OSF wheel. The caliper does seem to rub at one particular point https://photos.app.goo.gl/2nSQm1TwZ5FdmbUL8

The other side also rubs a bit, but with more consistency across the whole rotation https://photos.app.goo.gl/omWDmz1hFetnCx2d6

Turns out the noise was coming from the OSR wheel. Fixed now, but required a new caliper and pads.

While you're there Lewis, I would look at the rear ABS bracket on the stub axle, mine was so rusted it had taken the ABS ring off the disc and it was causing friction on the rear discs, they're only £16 from RPD.

Thanks for the tip @suj is that something I can check on my driveway with the wheel off?

If you feel comfortable taking off your disc (36mm socket in centre) it's easy enough.

You can look from behind also, but another way is take off the caliper from disc and spin the disc, there shouldn't be any resistance it should spin freely, if you have resistance it most likely will be a rusted ABS plate.

Also can do similar with caliper on to check handbrake cable, as mine was also seizing so not fully retracting when you take handbrake off.
