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?

Four piston caliper is a direct bolt on for pre 2000 315.

I would go for this one if it was my bike ;-)

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.

Which aftermarket pads do you use on your 04?
