Caliper Bolt Kit | For Mechanical Trailer Disc Brakes

Couplemate™️ supplies this disc kit with:
- 1 x 7/16″ UNF zinc bolt
- 1 x Zinc flat washer
- 1 x Zinc shake-proof washer
When it’s time for repairs and maintenance, remember to install it in this order: Bolt head → Flat washer → Shakeproof washer → Caliper bush.
