    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

brake pads too thick?

ok, just tested the caliper on an old RF900 disc, 5mm thick but it measures 4.7mm due to wear. the caliper works fine now, releases the disc when lever is pulled and released, so something has to be shaved. gonna try the "material off the pistons first see how hard that is, if not then a trip out to get the pads skimmed
 
Crazy to skim 4 pistons per caliper. I'd deal with the pads.
 
I would deal with the pads also rather then the complexity of those pistons.

But more of an issue with me is do you still have residual pressure in the hydraulics with the thinner disc relieved by opening the bleeder?
 
You sure the pistons are all the way back in to the cailper body. Maybe cracking the bleeder as suggested would give you that little bit more you need???
 
SUCCESS......... i have shaved off 1/2 mm off the "material" on each of the pistons. it is almost like hard wood sort of composition and was easy to file down.
All back together again and bled through and it works perfect.
Jack, i think the residual pressure was due to the pistons being pushed out but not quite reaching the roll back point so they were being pushed out but didnt have the rollback action from the seals, so they just sat there until pressure was released,(by the bleeder).
anyways, all sorted now, many thanks for all your help and ideas everyone.....
