scottie_b205 Posted December 28, 2012 Report Share Posted December 28, 2012 I have a 1999 montesa 315r and I am not impressed with the front brake performance. I have read some discusions on this website pertaining to getting the 2 pot brake better. I recently saw a '97 315r for sale that had stock forks and a 4 pot brake mounted. When I went to email the owner it was gone and the listing was deleted. What I would like to know is if the 4 pot is a direct bolt on? Will it line up with the disc?

tlrmark Posted December 29, 2012 Report Share Posted December 29, 2012 Four piston caliper is a direct bolt on for pre 2000 315. Quote Link to comment Share on other sites More sharing options...
guys Posted December 29, 2012 Report Share Posted December 29, 2012 I would go for this one if it was my bike ;-) http://www.splatshop.co.uk/xblok-billet-racing-caliper.html Quote Link to comment Share on other sites More sharing options...
chuck4788 Posted January 8, 2013 Report Share Posted January 8, 2013 I think the 4 pots are AJP calipers like my 04, but I don't know if the mounting bolt pattern is the same as the 2 pot caliper. Some aftermarket pads have a higher coefficient of friction than OEM so would provide lighter lever pull. After market rotors also may have a different coefficient of friction than OEM. Also a smaller bore MC would lighten lever pull. I have the opposite problem on my 04 with aftermarket pads; the low speed braking is very grabby, at low speeds the bike stops with very light peddle pressure.

guys Posted January 8, 2013 Report Share Posted January 8, 2013 Which aftermarket pads do you use on your 04? Quote Link to comment Share on other sites More sharing options...
