Rear Brake Dust Guards/Shields
Hi
Has anyone had any success sourcing new ones and replacing these? Mine are completely corroded now and disintegrating.
They had caused some pretty horrid noises on the rear brake discs as they corroded and deformed, which were cured by pushing them away from the disc from time to time - bit now are falling apart.
Or - should I just remove them - do they serve any great purpose? (I assume they are there for a reason)
I am about to replace pads and discs all round - so now is a good time to get them. I've found a couple of places in the UK that sell them - but want £60 each for them :-o I can see them for sale in the US for $20 - quite a difference.
Any advice much appreciated!

I would just remove them, it'll improve cooling but it might give more of a chance for some stone to get caught behind the disc.. However likely that may be.
... haven't missed them since.

Yeah they must stop the heat from the brake discs radiating into the rubber boots of the balljoints. They surely act as a cooling fin/hestsink a bit too as they'll absorb heat generated and get cooled in the passing air. I wouldn't remove mine anyway, I know the rear hub bearings get hot as it is when on track.
If you do get replacement ones you won't be able to fit or remove your old ones without either removing the hub and fitting a new bearing or by (what I'd do) cutting the old ones off and then cutting the replacements to get them into place.

I ditched mine. Keeps them cooler so I can go longer on track. Slight, but minimal risk of something flicking into and damaging the disc, but hasn't happened to me for thousands of miles. I wouldn't worry too much about replacing them.
