Calipers Introduction

A huge range of calipers to suit your requirements.

We have a huge range of 2 piston, 4 piston and 6 piston calipers, both two piece and monoblock for any application, to suit brake discs from 170-330m. In some cases, the calipers are direct replacements for standard discs and forks, but if not, mounting brackets can be provided to suit both standard and oversized disc sizes.

Brake pads for all ISR calipers can be obtained through your local EBC or SBS stockist. Alternatively, we have pads in stock for next day delivery. Click here for details.

Although the calipers are different sizes, they share a number of features which make it obvious that ISR have put the user and performance at the centre of the design.

1. Pad per piston design - The increased number of leading edges results in greater initial bite and a more responsive braking system.
2. Captive brake pads - The pads are held captive in the calipers when mounted on the bike so that if the locking pin is lost or broken, they can't fall out, so increasing safety and preventing loss of braking performance.
3. CNC Machined from billet aluminium - Allows a lighter design whilst maximising the strength of the calipers.

We’ve included details of the most popular models on the site but if you don't see something which exactly meets your requirements, then please contact us because whatever you want, however weird and wonderful, it is likely that ISR can make it!

To all those existing ISR caliper users...
We can supply replacement brake pads for all the ISR calipers, even ones you may have bought 15 years ago. A number of compounds are available to suit different purposes.

If you change disc size or bikes, we can offer mounting brackets for all ISR calipers. See braking accessories for details.

Alternatively, if after years of faithful service you feel that there is a loss of power, before throwing your calipers away and buying some new ones, we offer a caliper rebuild service to replace any worn components.

Please remember...
When ordering calipers you need to tell us which side the caliper mounts because all designs have left and right hand versions.

We also recommend that you upgrade to a quality brake line to get the best out of the increased braking performance. It will help to transmit more power from the master cylinder to the caliper.
