Default brake return springs

Has anyone added brake return springs to the stock master cylinders of the 14? I've had a dragging brake occasionally and had trouble replacing brake fluid from the calipers up. When I put a bungee cord on the top of the pedals to pull them back, the fluid flowed much better.

This seems to be a fairly standard mod on other RV's. Just wondering which springs and retainers to use...

Also wondering which is the best hi-temp lube to use on the brake pad guides

Thanks for any suggestions

I used these parts for brake return springs on my RV-10.

Just beware of shaft wear issues. I started out with additional return springs for many hundreds of hours (or a thousand hrs?). I removed them long ago. I think the best improvement is a single bolt through both sides of the pedal.

A 1/2" nylon spacer on before the spring will eliminate this issue.

The spring mod works great on the -14.

Default Brake springs

We’ve been just replacing them with Grove Master cylinders. Cures all the Matco dragging issues

If the alignment or shift of the alignment during brake application causes misalignment, the shaft will hang up or wear. If the alignment is proper, springs are not needed.
