Are they a straight swap using exisitng rotors and forks? Am still having shuddering on braking so would like to change calipers however dont want to change rotors as they are new...
More detail required... What model? What Forks? What Calipers installed at moment? What rotors (discs)?
Try cleaning your existing calipers first. Sticky pistons due to crud build-up also give the same symptoms.
Sorry On a 2004 ST3 Standard other than now running EBC rotors of same size as standard. EBC HH sintered pads Calipers have had a total overhaul Am wanting to try four pots hence the 749 query as I understand they are the same bolt to bolt size wise but not 100% about that and also not sure if they would need a different offset
Replaced steering head bearings about a month ago - have done 2000 miles since so will check again but not expecting them to be duff tbh
Are you using EBC HH pads BTW? I found them very grabby. I changed from EBC HH to Carbone Lorraine and found a big improvement in both initial bite and feel. Also, after doing the head bearings on mine, after about 500 miles, I had to re-torque the head bearings again.
I have fitted 4 pad calipers to my ST4S that came from a 996R. The calipers should be the same dimensions as yours and the forks will be the same as mine so it will work. The difference over stock is significant. Agree about the headstock and caliper checks first .
Maybe not duff... but correctly adjusted ? Wheel bearings definitely 100% ? Just a good engineering motto - always do the cheapest things first...
