Hello

after recently changing my pads I had a look at the condition of my callipers…. It wasn’t great. Two pistons per side where seized and one of the others only actually half the contact face left. I’ve had a look at putting new seal and pistons in but at £25 per piston and seal set the thought of £200 got me thinking about new callipers.
Obviously when putting new callipers on I need the same mounting bolt holes dimensions and the same sort of size to prevent having to put a larger brake reservoir on.
Anybody know what callipers bolt straight on the 1989 H1 forks. Any help is greatly appreciated.
I hear ZZR 600 might work and also ZXR750 H1 may can anybody shed any light?

This post is nearly two months old, so it is likely that something has been done about the calipers. But if it is of interest, calipers from the L range could be used. They have the same hole centres to bolt to the forks. The pistons are slightly smaller in diameter compared with the H, so that means there will be ample capacity in the master cylinder.
