Title: C15 brake pedal return spring location
Post by: gusmagicbus on 28 January, 2018, 20:17:40
I'm rebuilding a C15 SS80 and just can't figure out how or where the brake pedal return spring fits. I have managed to fit it where I thought it might work but there's not enough spring pressure to return the pedal. Any advice or photos would be ace. Thanks.

What year is your C15. Most of the later ones were fitted with a spring concentric to the brake pedal pivot which I've found is not that strong.

It's 1964

It should have the concentric spring if from 1964.

My B40 didn't have a return spring at all when I got it. The rear brake shoe springs returned the pedal. However on rebuilding I managed to source a concentric spring which is strong enough to return the pedal. The early models of the B40 and I assume C15 had a standard expansion spring attached to the frame and brake pedal.

Thanks all.  I've managed to sort it.  In the end I  slackened off the brake arm nut a little at the rear hub which allowed the brake shoe springs to assist the return spring in returning the pedal to the correct position.

Cheers
