How 'free' Should The Back Wheels Spin?

[benl1981]

Just replaced my rear R33 pads yesterday. I noticed that with the handbrake off it was quite hard to slip the pads out.

Put the new pads in after gclamping the calipers back.

The wheels spun fairly freely.

Once I pumped the pedal a few times I tried again (bringing the pistons up). The wheels would then spin but almost as soon as you stopped spinning it the wheel would only spin for abother second if that. There was more resistance which I guess is normal..

Just wondering if other people have found the same..or if there is an adjustment for this.

Thanks

C'mon - somebody please. It isn't excessively wearing the pads but I'm just wondering if this could be costing power or fuel economy.

Anybody whose done their rear pads would know

Cheers

Shouldn't really be any difference, because you are having to turn the halfshaft into the diff - doesn't matter if the pads are back or pumped up.

Hi Ben

I recently changed all pads and I also noted that the rears required a LOT more effort to turn than I expected. I shrugged it off as just one more thing I don't understand.

I hope/assume it's normal...?

Its all normal guys.

The discs will never run 100% true and will grab a bit on the pads.

The front wheels will be the same too.

Yeah thanks my fronts spin a lot more freely. I guess you dont have a differential (i.e gears etc) to turn on the front.

I guess if it was abnormal youd see your pads wearing quick/smell?
