The mounting bolts for my front callipers Ones shouldered and ones straight Is the shouldered one supposed to be at the top or the bottom of the calliper?
Yeah, pretty sure mine are top, the shoulder in your caliper should confirm that. I got a new caliper for one of the front discs, and it seems they've done away with the shoulder (annoying as I had to buy another bolt).
It seems it depends on year However to add to the confusion my van has ate callipers on it but for its year they should be girling. Ones knackerd too much to refurb but the other ones fine. I’m not sure if the good one is the left or the right hand side. Just been reading this on the samba https://www.thesamba.com/vw/forum/viewtopic.php?t=556225
So it seems the shouldered bolt to the top would make my good calliper a left hand side However that puts the piston cut outs at the top and according to Bentley they should be at the bottom.
ATE on my ’77 too. Why can’t you turn the pistons if the cut outs are wrong? By the way stainless steel anti-squeal shims that locate in the cut outs are available from Brickworks – but I guess you knew that. https://www.brickwerks.co.uk/t3-par...m/anti-squeal-shim-t3-early-ate-calipers.html
It' a Varga one from Cool Air. One nipple from memory. Neither my old ones, or the old ones had anti-squeal shims in them? Are they still needed? Guess I'll soon find out!
That’s my intention I just wanted to make sure I’d got the good calliper on the correct side I’ve the pad backing plates here but the tabs that locate on the piston cut outs are flat with the plate So they have either never been punched out or they have been flattened back down at some point. They must be to stop the pistons rotating in the bore .
They’re needed to reduce squeal and to locate the pistons – if the pistons have the cut-outs, and they should.
Bentley shows the shoulder bolt at the bottom for all years but different tightening torques. I don’t really see that it makes any difference whether the shoulder bolt is at the top or bottom as long as the cut-outs in the pistons are at the bottom.
Ok. Odd that mine didn't have them fitted and never squealed though? New caliper doesn't have the cut out either.
Yes, the parts list has M14X1,5X34 for the shoulder bolt and M14X1,5X37 for the plain bolt. It also shows the shoulder bolt at the top, which is the opposite to Bentley. http://www.oemepc.com/vw/part_singl...ubcategory/52000/part_id/3694485/lang/e#sec_3
