Brake Caliper wont go back on?

I took my forks out for an oil change, no problems, then I had to put them back on my bike- this is the first time I have done this but i just followed the Haynes manual-- everthing was going ok, forks back on, wheel back on, lefthand caliper back on (left as I look at bikes' front headlight), but when I tried to put the right hand caliper back on to the wheel it would not fit, I need about 2mm more cleareance in order to squeese the caliper onto the disc? What have i done wrong?

thanks

Re: Brake Caliper wont go back on?

you wiggled the right caliper as you installed it. The extra space you gained on the right caliper was taken from the left caliper. Take a large flat screwdriver, put it between the pads and twist till you get more clearence. Then install.

When talking left and right, always do it while sitting on the bike. It works for cars also. The only exeption is when working on a car engine. It is always refered to as looking at the engine from the front of the car. Even for transverse engines.

Be careful with the screwdriver otherwise you'll chew up your pads. I use a piece of wood to pry the pads apart.

Re: Brake Caliper wont go back on?

thanks, but its not the pads- the pads go around the disc--no problem. its when i try to position the caliper on the lower casting ( where i screw it onto the lower casting with semi permanent threadlock?) I cant get the caliper on to the lower casting because of the 2mm non-clearance? i think i havent lined one of the forks up correctly????

Re: Brake Caliper wont go back on?

Maybe you didn't seat the axle correctly when reinstalling the wheel? You have to pump the forks up/down a few times before tightening the pinch bolts.

Re: Brake Caliper wont go back on?

Do you have the spacers in the wheel on the correct sides?

Shouldn't. I'd double check the spacers.

Hi CJ550,

where exactly is the "2mm non-clearance" ? - front to back on the caliper mounting bolts ? up/down on the caliper/disc itself ?, or in/out on the caliper mounting bolts ??

Your guess that you have not lined something up correctly is probably accurate. Assuming it's an alignment issue with the caliper mounting bolts I'd suggest that you back-off all the nuts/bolts on the lower fork legs (axle pinch bolts, R/H caliper, etc - just crack them off 1/2 turn or so don't undo them completely) to allow you to wriggle things around a bit which should enable you to manoeuvre the caliper into the correct spot - once you get it there don't do the mounting bolts up tight until you've bounced the front end up and down a bit and rolled the bike backwards and forwards to try and get everything stettled back into place correctly. Then follow the Haynes manual for the tightening sequence, then tighten up your caliper mounting bolts...hopefully that'll get you sorted.

Cheers, Spanky

P.S. Raising the fork legs 8mm would not have caused this problem - so long as they are both exactly even...from another angle though 8mm is a fair change - I did 5mm on my 929 and found it was a good compromise, do you have a steering damper fitted ?.

Re: Brake Caliper wont go back on?

Ah! got it.
Loosen up the axil pinch bolts on the LEFT side (the side that you are having trouble with. Also would be the driver's side if it were a car built for the U.S.). Bounce the suspension a few times, or simply pop out the fork bottom a bit. Install caliper. After you install both sides, keep the pinch bolts loose on the left side (the side without the bolt that goes into the axil), with the front brakes applied, bounce the forks up and down a few times, then tighten the pinch bolts. You're all set.
