*Koxx hydroxx 2 Jack * Posted May 24, 2009 Report Share Posted May 24, 2009 Hi ,ive recently been told that i need little spacers to set my disk brakes up correctly and make sure that the rotor is in the middle of the caliper . i can see the logic behind this but have always thought that the pads are self centering . can someone please tell me how to set them up and if i need these spacers where i would get them from .Many Thanks ,Jack .

JT! Posted May 25, 2009 Report Share Posted May 25, 2009 Yeah you need shims (washers) to make sure the rotor is right in the middle. Quote Link to comment Share on other sites More sharing options...
esfrost Posted May 25, 2009 Report Share Posted May 25, 2009 You should also check out this page http://www.hopegb.com/page_mep_force_4.html, there are some very helpful videos, on how centralise the pistons, bleed the brake, shortening the hose...

Guest Posted May 25, 2009 Report Share Posted May 25, 2009 undo the caliper bolts (the bolts that hold the caliper to the bike) pull the brake, then tighten the bolts whilst holding the lever still (so the pads are hitting the rotor still) this should work, its how cycles UK set up there disc's aswell.

Muel Posted May 25, 2009 Report Share Posted May 25, 2009 For all hope brakes the shims are to make sure that the rotor is in the centre of the slot on the caliper, then the pads should adjust themselves over time to hit the rotor correctly. If they don't either the rotors bent, the mount hasn't been faced or the pistons are sticking. To free them off, take the caliper off, pump the lever to push the pads out and use a small brush to lube the pistons with some Dot oil, then push them back in with a screwdriver, wipe the caliper out and refit the pads, push the pistons right back into the caliper and when you pump the lever they should move out the same amount, so if the rotor is in the middle of the slot they won't rub.

*Koxx hydroxx 2 Jack * Posted May 25, 2009 Author Report Share Posted May 25, 2009 Where would i get shim's from ? Quote Link to comment Share on other sites More sharing options...
psycholist Posted May 25, 2009 Report Share Posted May 25, 2009 If you want thick shims (They're really washers ) try B&Q or any hardware shop. Then for fine adjustment the thinnest shims here: http://www.chainreactioncycles.com/Models.aspx?ModelID=356For what you're getting the price is ridiculous, but aligning the disk is a job that you only need to do once if you do it right. Then the disk should work perfectly for years... Quote Link to comment Share on other sites More sharing options...

Google it.First you need to face your mounts both front and rear, any bike shop would probably have that tool, I know halfrods do as I am working there. FAce the mounts so your rotor is not twisted by a calliper. Then if the brake pads are not in line with the rotor or not in the centre put the washer or shim under the bolt you need to move out futher from the frame. Some times your need to put more shims to make it in the centre. Also once set up, it is going to take some time for brake pads to bed in, so be patient. Recommend using google, hope website and help you are provided here! If you still don't understand I can try to take some pics and help you Quote Link to comment Share on other sites More sharing options...
