Title: Bearings question
Post by: Steve_B on 14 September 2008, 16:14
Have just replaced one of the rear brake discs after replacing the bearings. It spins freely, but I can hear a slight sound as I spin the disc, must be coming from the bearings. Doesn't sound bad, but I just wondered if it was normal? Paranoid about the bearings seizing or something silly, packed in the grease to bearings as instucted and 99% confident it's fine. Just really don't want to mess this one up!

Quick answers greatly appreciated, have to do the other one before it gets dark!

Are you sure its not the pads binding on the disc slightly as its new??

Id put the wheel on, drive it round the block and pump the brakes a few times

Pads aren't on yet, just that I can hear the bearings spinning and wondered if that's OK?

I'm spinning the disc by hand

Probably fine, mate as along as they aren't making a racket.
Pop the pads on and take it for a drive round the block if it feels OK and you can't hear the bearings take it for a drive on a faster road and if you still don't hear anything :afro: job's a goodun' if the wheel falls off well then you know it wasn't right.

there will be some noise, even the newest bearings, after all its a moving part, as long as its not over tightend then should be fine. best way is to drive it and listen. but dont get too paranoid, get someone impartial because i can guarentee youll hear something that just isnt there lol.

Indeed.

I got so paranoid about mine I had my local garage change mine... twice, I hardly ever went over 60 and when I did I shat myself... Was nothing in the end really, just my paranoia  :laugh:

old perished tyres will also make a similar 'roaring' noise.

guys at work ribbed me for thinking i had a front bearing gone... it was just the sh!tty old tyres!

My tyres aren't that bad a make being Michelin. Front are close to being replaced now, so I'm on the look out for cheap alloys.

put the wheel on and give it a good wobble.

if it does wobble its not right. take wheel off and start again

if its solid and doesnt wobble its kool  :grin:

Cheers guys, sounds like it's ok. Only got one side done in the end, only had an hour of daylight left when I'd finished it. Have to hope it doesn't rain next weekend!
Another question, as I opened the bleed nipple to wind the piston back will I have to bleed the brakes after? Can't see how air could get in, but don't want any nasty shocks  :grin:

There should be a little bit of play but not much.
