Hi all, Around Christmas my drivers side front caliper seized solid and warped the disc. For the time being I put a spare caliper on just to keep me moving. As I was going to do a scrapyard upgrade on the brakes anyway I decided to up the time frame and get 270mm sports disc's as I already have some rx7 calipers...... I can now see why its not a common upgrade, Its going to take more than a spacer plate to get them to fit.  :(
As a stop gap before I spend a week grinding, filing and swearing at the rx7 bits I need to make some spacer plates to move my original front calipers out so I can get the new disc's on.
As I've had my brakes in bits soooo many times lately (And have the skinned knuckles to prove it, :)  ) I don't fancy freezing to death dismantling a side again just to get some measurements.
 
So, Has anyone got a MK1 1.8 hub handy that they can get me some measurements off ? What I'm after is the distance between the caliper hanger bolt holes, The thickness of the lugs the hangers bolt to (ie, From where the hanger touches the lug, To where the bolt head touches the other side) and if possible, The distance front the center from the bolt hole to the point furthest back on the lugs (I've done a little doodle that I might be able to attach as I dont think I've described this very well).
 
If anyone can help It would save me getting frost bite, Thanks

It’s OK, I dismantled one side of the front this afternoon and got the numbers I needed, It was ruddy freeeeeeeezing out there…!!!

If anyone’s interested, "A"was 120.19mm, “B” was 14.15mm and “C” was 16.31mm.

This all means that for clearance It needs to be a slightly more complex shape to move the caliper around the disc a few degree’s (Well, 20ish) So I’m going to have to make the plates ON the car, Using plywood to make a template I’ll then use that to make them out of 13 or so millimeter mild steel or HS steel if I can find a usable chunk of it in my brothers workshop (Also need to make some 16.31mm thick “top hat washers” to weld to 'um).

Just as well that I love playing in machine shops :slight_smile:
