4 Piston Caliper Service
Four piston calipers are high-performance braking systems found on sportier motorcycles. They deliver excellent stopping power but require more attention to detail during servicing due to multiple pistons and seals. Our 4 piston rebuild service ensures all pistons move freely and evenly, restoring maximum braking performance. With ultrasonic cleaning, new seals where needed, and a full reassembly and pressure test, your caliper will be brought back to like-new condition.

- Seized bleed screws – No action needed, just send them in; we can usually remove these at no extra cost.
- Snapped bleed screws – We can normally repair these without thread damage. Cost: £10 per screw.
- Thread repair required – In stubborn cases, repair may cost up to £35 per screw. An accurate price will be confirmed after inspection.
- Seized jets - No action needed, just send them in and we should be able to remove them free of charge.
