Brake backing plate

Discussion in 'Mech Tech' started by S1mon, Jun 2, 2018.

  1. Got a new rear back plate old one fell apart from the rust.

    Adjusters don’t fit.
    Drilled out to fit star adjusters. They now fit.

    Put brakes back together.
    Drums on star adjusters down to min
    Aligned pads etc.
    Put drums on and can hardly turn the drum.


    Any ideas thanks!

    Either the slave cylinder pistons aren't backing right off or the handbrake spreader bar isn't sitting in its slot properly

  8. Little up date mate had a look couldn’t fix the problem either backing plate is the issue.
    Need to speak to supplier
     
  9. Are they VW Brazil plates?
     
  10. Poss site says correct ones late bay and Brazil.
     
  11. I may be missing something, but is the handbrake cable fitted? Might be that I can't see it from the photo...
     
  12. Sure it`s not an Early backing plate ??

    I`ve got a couple of spare genuine n.o.s plates if you need something to compare yours to but they`re few and far
    between .

  13. Tried with handbrake cable on and off still same locks up. Mate came round and double checked and said he couldn’t work it out old og backing plate was working before but had rusted through
     
  14. Hope you get it sorted - I noticed the thread because I have to do the very same thing in the coming days!

    The pistons don’t look to be fully retracted to me, compared to this.

  17. Compared to other side measured pistons and same other side works fine pistons seated the same.
     
  18. Attempted this again tonight.
    Did everything right I think.
    I’ll post more pics in a mo.

    Brakes bind with star adjusters on lowest setting new backing plate again star adjusters didn’t fit in the holes had to ream them out.

    Seems when I tighten the drum to the hub with the two small bolts it starts to bind and if I adjust it it locks.

    I found an old set of brake pads and it does the same with those as well as the ones that were on there.

    Any ideas.

    Mucho thanks in advance
