-----Question-----
I removed the caliper to clean the break pads, in the course i operated the break handle which has now closed the opening (has brought the two cylinders to the front of one of the breakpads which is still in the caliper blocking the space for the other pad which is hanging lose). To make it worse i opend the tank cover so tht the pressure could be released which did not help and then removed the wire connecting to the caliper from the handdle, oil spilled all over but the cylinders refuse to budge, there was one more nut in the caliper which i loosened and didnt help either. there are not many professionals here in india who can fix. hw can i bring it back to original condition. can u please help.

Hi Vivek.

First thing; reassemble everything.

Next; with the caliper installed and the wheel removed, get a flat, wide screwdriver between the calipers and begin to gently, but forcefully, pry the calipers apart.  It will require a bit of real effort, but you can pry them apart.  Once they are open enough, you can get a small prybar in there to apply better leverage and open them up all the way.  THEN install the pads and bleed the system.

Also, get yourself, if you haven't already, a repir manual for the bike.  I always recommend the factory manual if you can get one.

Good luck and ride safe.

Hi Vivek.

You fill the fluid through the master cylinder.  There should be detailed instructions on type and bleeding proceedures in the repair manual.

As far as performance, as long as you bleed the brakes properly, there should be no problems at all.  And make sure that you do not touch the brake pad surfaces with hands or oils.

Good luck and ride safe.
