Re: ORJ's Rear Brakes

Back on the job and on with the saga - SJ had not got the seal kits in stock, but Steve assures me I'll get them this week. I was planning to do one side at a time but if I can't get the seals I'll get both sides done and ready for the final rebuild. So I've whipped off the right hand side caliper to refurb it and the handbrake mechanism as well. Its not very nice - but I had taken it off when I replaced the handbrake pads so I knew that...
The handbrake mechanism pins came out the usual way, screw in the little bolt that usually hold the centralising strips, put its end in the vice and gently tap the caplier:
The handbrake mechanism was pretty corroded and not very nice. Clevis pins were seized in place. And a PO had put a washer under the head of one of the clevis pins which made it very awkward to press the old pin out in the vice - why? if you are going to use a washer then put it under the pin where it will do some good.
They came apart eventually...
With all the parts seperated my newly aquired wire brushes were used to clean them up, and it was out into the garden for a coat of Silver Smoothite - again trying to avoid painting the dog
Then back to the caliper. I used the air line on it and one piston came out instantly. Good oh I thought - and look its in pretty good condition. Checked it with a magnet and its stainless. Blimey I thought a PO has done something right. That was until I checked the one still stuck in the caliper - it was magnetic so mild steel. So a PO had changed one piston in the caliper. Good grief.
The other one is moving slightly, so the caliper is marinading in some penetrating oil and WD40 - should get it out later.
Onwards!
