HI, I was wondering if anyone knew of how to remove bonded brake shoe linings off the brake shoes? I haven't been able to find anywhere on the net to assist, which is odd, but having no success trying to do it myself. Many thanks, Jeff.

Geoff,

How old are the brake shoes??

If they are pre-1990, they will incorporate asbestos and the usual precautions will need to be taken due to the risks associated with this material.

If you enquire at local brake specialists [truck/bus repairers in particular], they may able to arrange relining for you or refer you to someone who can. I would be very surprised if you cannot find someone in NZ who can do this for you.

Hi and thanks for your reply. Yes there are definately people around who will reline them, but I have some new linings here from Flying Spares and all I need to do is get the old ones off before I can replace them. It's proving to be somewhat difficult. What I was hoping to do is just do them myself! Maybe I should just leave it to the experts!
Thanks

Having worked for a company that specialised in the manufacturing of brake shoes I can tell you that you are best to leave this job to the experts as the process requires that the old friction material needs to be burned off (Lots of unhealthy smoke) the shoes then need to be shot blasted to clean them, they then need to be checked for straightness, dipped in an anti rust solution at which point they are then ready to have the new brake material bonded in an oven at high temperature. The brake shoe material is clamped under pressure to ensure an adequate bond. Alternatively, the material can be rivetted on.
The shoes then need to be ground at a set radius so that they fit inside the brake drum.
As I said, not a job for a DIY'er. If you are in New Zealand there are specialists still available.
