Hi, yesterday my I obtained a really bad grinding noise from the rear of my car. I've checked the rear brakes and the osr disc is full of surface rust, yet the nsr looks fine. I know I could do with new discs and pads anyway, but do you think that will solve this issue? I know nothing about brakes and was worried something maybe up with the caliper for just one side to be really bad? Also any idea how much new discs and pads fitted would roughly cost? The fronts need doing too really but they can wait for now, I just want to get rid of the dreadfull grinding as it's REALLY bad!

All help much appreciated.

I think it unlikely that just replacing the pads and discs will solve this - sounds like a seized caliper.

It's the rust on the disc edge that causes the grinding noise and the fact that there are no return springs on the handbrake mechanism. It will be worse in the winter months and the pads can stick to the discs as well

The only clear remedy is to fit pull off springs to the handbrake cable and file off the rusty disc edges, renew the discs if they are well gone though.

Sounds like a seized caliper/piston on the OSR brake.

Sometimes it goes the other way and they bind there instead and don't fully release.

Causing heat build up.

They are very prone to corrosion on the rears on these cars. Cr@p design :yes:

But if you have one shiny disc and one rusty one it would

suggest to me that the brakes arent functioning on one side and cleaning the disc through normal use.

Although they nearly always corrode like a Mo-fo after a fairly short while.

They don't really do much other than keep the car balanced when braking

The fronts do almost all the work on the Fabia :yes:

I'd recommend this supplier. Decent prices and very good service.

here's a useful link---> http://www.jorily.com/catalog/index.php?main_page=product_info&cPath=131_7_17&products_id=960

When new ones are fitted the calipers/pistons should be cleaned up and given a once over by any decent fitter.

With new discs and pads and a mini "service" and clean up you should see a favourable result.

Mine were noisy and sticking I replaced them using the parts in the link above and so far everythings good.

For gods sake dont let Kwik-Bodge anywhere near it. Find a good indy.

But the OP said "I've checked the rear brakes and the osr disc is full of surface rust, yet the nsr looks fine. " In that context I don't think it's the usual edge corrosion he's talking about. If the handbrake was sticking on the disc would be clean. Sounds to me more a caliper seized in the off position.

Your sure right David, does sound like a sticking caliper, in which case I would slacken of the handbrake cable, dismantle the caliper and pads and turn the piston manually in and out to free it, then re-assemble everything and drive it for a while, hopefully the piston will start working and adjust up ok. Then re-adjust the handbrake if all is well. Might as well de-rust the disc edges while he's at it.

If you really, "Know nothing about brakes" for Gods sake, take it to someone who does. It's clearly a seized caliper.

Thanks for the replies. Yeah it's not just the usual corosion on the edges, it's the actual face so seized caliper sounds likely. I'll call my local VAG specialists tomorrow to try and get it sorted. Is it likely to cause any damage if I drive it other than to the disc or pad?

Thanks again.

hey, i have grinding from mine too but not from the same source as yours, like a previous reply mentioned ts the rust around the edges which cause the grinding which i have, any idea how i could get this to stop?

thanks didn read the whole thing lol i have four new discs fitted about two weeks ago, so a bit strange about the rust really.

So Apogee can you make this thread http://briskoda.net/...ssue-on-my-vrs/

a sticky, everyone is aking about it, especially in the winter.

If you had discs fitted only two weeks ago these aren't going to be very rusty yet. If you've got noise then something's been done wrongly. Take it back!

thats what i thought, but on expection today the discs are fine tooks the wheels off and sanded down a slight build up of rust on the hub of the alloy, seems to have worked for now

Now that is strange, I would not have expected doing that would have sorted out your problem - I think that you should either take it back or find out exactly what your problem is/was.

So what you're suggesting is that the wheel wasn't seating properly and wobbling when it rotated, thus hitting something somewhere - now it's cleaned it's stopped doing that - might be OK...
