The rebuilding of drum brakes takes an element of discipline. The shoes have to be relined oversize. The brake drum may have to be machined, housings repaired and the backing plate linkages set in place. When machining, everything is either machined on bearings or spigots to ensure accuracy so that when you apply the brake, the entire shoe touches the drum creating a good braking effect.
When machining the linings, this is done in situ with the brake cams slightly open so that it is in the working area. I machine these to the same diameter as the brake drum. The drum is usually machined between centres to keep it perfectly concentric.
Look at the slide show on the right.
I can clean, blast and repaint the disc centre so it looks much like the factory finish. If the disc is worn, I can send it out for re-grinding or can linish it here in the workshop.
