Rear brake pads
Discussion
Just been checking all my brakes. On the rear pads is one pad thicker than the other? Just that mine are thicker friction material on the rear side of each rear brake. Would seem strange if they both wore that way.......... then again TVR and strange in the same sentence isn't so odd
Is yours an aftermarket upgrade, or S4 brakes? S3C had drums AFAIK.
I think the pads should be same thickness. If they are sliding caliper type like the front, then thinner pads would suggest sticky slides (because then the piston side does more work, if the caliper sticks "Off" or the outer pad wears away, if the caliper sticks "on"). Could also be the handbrake dragging slightly.
Not sure of the exact setup though so it might be normal...

Had a look at your pictures TVR of brake changing but coouldn't see if they were the same thickness or not Ah right!
I think the shoes do start off the same thickness but because one is leading and one is trailing, one of them therefore wears quicker. On the TVR that would be the em... (goes away to look at his own pictures to remind himself if the cylinder is at the top or bottom) the rear one!
If you look at the first pic in my sequence (ie this one
you can see that the back one is indeed thinner than the front.
Mind you, mine had the handbrake sticking on for a while (on the side I photographed) so that might have had something to do with it!
Hope this helps.

parts list number................
neither work... I need to get the shoes ordered so my helper (aka my Mum's husband) can help me fit them on New years Eve.... They are Ferodo FSB176A.
OR
Go to a motor factor (or indeed Halfords) with the old ones, and ask for brake shoes for a 1986-ish Ford Sierra 2.0 or 2.3 or diesel. I think I recall that mine said they fitted the estate as well. Compare the new ones with the old - I believe that there is one Sierra model (can't remember which one it is) that has a larger diameter drum and hence bigger shoes. Make sure the shoes are the same width (ie from the backplate across to the front of the drum) as well.

Good point.
I didn't think of that - I was the other way round, I had to change the shoes because a cylinder was leaking... so replaced the cylinder on the other side as well.
In my case I ended up replacing a bit of brake pipe as well because the connector was siezed into one of the cylinders, but still worth doing.
