Idiot Disc Brake Question

coomber · Jun 21, 2012

Hello helpful people.

I have a Clarkes S2 disc brake that I think is excellent. My mate borrowed the bike and the rear brake wasnt working so well, took the wheel off and must have inadvertently pulled the lever.

Now the pads are too far together to put the disc (and therefore the wheel) in properly. Have tried pushing them apart but they wont move enough.

What do I do?!

Take the pads out I guess and try and poke the pistons back?

Sorry I am pretty unused to these new technological advancements on my bikes.

I did this to mine avid 3's recently so would be interested in the outcome

I fear a brake bleed is the way out

A large flat bladed screwdriver (wiped clean of course!) normally does the trick, or maybe a wide tyre lever, which is less likely to mark the pads.
Should be easy to push them apart.

You can take the pads out and walk the pistons back with the round end of a spanner (11mm or so seems to fit well).

Or alternatively, if you have a bleed block (such as an avid one) you can squueze that in there.

You can also jam a flathead screwdriver in between them but this isnt massively advised as can damage pads.

Well pads are a tenner and that's cheaper then a new brake so will give that a go.

Thanks for the tips - will report back over the weekend.

This is what i use (only a couple quid but you get them with avid brakes and you may get one form your lbs free? They say for use with elixir cr but its only plastic so its malleable to most brakes).

I'm the same as cyfa - got my pad spacer with my avid brake. Used it for just this reason on my brothers hope and worked a treat.

open the system then force pistons apart

Just open the pads out with a flat bladed screw driver to push the pistons back onto three caliper. If you push them too far back you'll need to pump three brake a couple of times before it works again.

This happens a lot of you transport turf bike with the wheels out.

I use a pedro tyre lever as its quite robust but being plastic wont damage anything :?
Take the pads out first[why not,its quick and makes it easier]
