Rapid, uneven rear pad wear - SV650.org

aesmith · 30-06-14, 03:59 PM

Hi,

I've just had to replace the rear pads after only about 6 or 8 months (say no more than 7,000 miles). Two things strike me, firstly that seems a very short life, what sort of mileage to others get? Every time I've checked the wheel turns freely with no binding, also checked by feeling the disc after a journey and it's never more than very slightly warm.

The other thing is that the pad wear is not even, the pad on the piston side is much more worn than the other side. It seems to me that this means the caliper isn't sliding properly, but I can't feel anything binding when I removed and refitted the caliper. Could there be something worn that means the caliper feels free to slide, but doesn't actually do so in real use?

Pointy S K6.

Thanks, Tony S

Depends how much you use your rear brake but I replaced my rear pads when they fell apart, was nowhere near wearing them out (they had been in the bike for 5 years so 28,000 miles with 20,000 of those being me in the last year).

JP used to muller his pads looked at loads of times.
When he got it mot test they failed the stop light of the rear brake.
Next weekend when you followed him he road with the foot just resting on the back brake!
I didn't take the rise..... Much lol

Check out the side play on the axle.
Spacers and incorrect fitting of calipers and there mounts does happen

Pointy.

I think NTECUK may be on to something. I'll check the spacers/washers on the back.

The pads that have just worn out were EBC GG.

When you fitted the new pads was it relatively easy to slide the pistons back into the caliper? If one of them was sticking it could result in the pads resting on the disk.

those should last 20k+ miles.

if its just the piston side then i would suspect that your calliper needs a proper service.
