October 1, 201015 yr I've just been having a bit of trouble getting a rebuild kit for the front Grimeca caliper of my 1999 315. Montesa don't list the caliper components in the parts list so identifying them is difficult as they are getting a bit old. After a bit of sending bits back and forth BVM have identified the caliper as the same as on the Beta Techno from the same era so what you need are the bits for that. BVM stock code - BE2002710000 - Caliper Kit Grimeca/Brembo - Seals BVM stock code - BE2569490000 - Caliper Pistons 32mm - Pistons ETA - You can back bleed the system with a syringe on the bench but only after you've removed the ball bearing under the bleed nipple. Once you've got rid of any bubbles keep the caliper a little lower than the master cylinder and replace the ball bearing. Finish off bleeding as normal with brake lever and tube on nipple etc. Edited October 1, 201015 yr by Wherry
