Production delays

Due to a unexpected terminal diagnosis, I am now required for care, 24/7, this has a massive impact on production capacity, due to this I am only selling from stock. I will get to all emails as soon as I can however there is likely periods of communications delays
Thank you for your understanding at this time difficult time.

Here you have one BSA brake Cam. Produced as a direct replacement for the original but made from solid stainless steel. Save on unreliable chrome plating! Stainless steel won't rust and polishes up beautiful! True fit and forget!


Just as the original this break cam comes with a grease nipple, these often snapped off with age and the grease holes often filled with dirt and grime making them hard to spot.


Part number: 42-5830


BSA fitted 4 different break arms to this Brake cam:

2 straight types: 42-5854 & 42-5886

2 offset / kinked: 42-6317 & 42-6353

We always recommend fitting a "star" hole break arm, instead of square, these give better adjustment, allowing for a better set-up brake.


Sizes for approximate reference purposes only

This break cam is designed to take the 3/8" (9.52mm) break arm

The cam's shoe contact area is 5/8" (15.9mm) high

The shaft area has a diameter of 1/2" (12.7mm)


Fitted to full-width cast iron hub front and rear wheels, this cam will fit a range of swing arm BSA models including:

A7, A10, A50, A65, B31 & B33


This item is made using CNC manufacturing in England by CPC Engineering with high-quality stainless steel.
