Thanks all for the kind comments. Boxey is right on the money with that comment.... I guess you pays your money and all that. Anyway as promised I managed to start to assemble the calipers on Sunday afternoon.
Emptying my box of brake bits, I carefully sorted through the pistons and seals to find any that might be rescued. I have complete replacements for both front calipers but the 993 C4 rears are hard to find.
First task was to get all the right sizes in the right order
After cleaning the caliper internals with brake cleaner and using cotton buds to clean the seal groove, assembly could start. Then blowing everything out with the airline it was onto the assembly. So in goes the actual piston seal.
Once in, a little clean brake fluid to lube the seal and a coating around the piston.
Piston squared up and the fitting tool used to gently wind in the piston.
Once past the seal the piston can be pushed home with the outer dust seal ready to be seated.
Right all in and onto the spring/ pad plates.
These were in need of a good clean.
The finished item ready to re-fit.
All done bar the bolts to secure the plates. These I have just picked up. I have used stainless Steel hex heads from a local machine shop. These will be installed with a little thread lock (Medium).
Lastly, good old PeterS came up trumps with getting my discs skimmed and ready for the install. Just need to replace the aging Braided Hoses with nice new Goodridge Hoses. I will make up new short metal hoses out of copper and fit everything once the oil lines have been address. The large 36mm spanner has just arrived, so the next job will be that great big Elephant in the room! Wish me luck as this next bit is going to get messy and scary expensive. I am putting stuff on Ebay to fund this like coals going into the fire box on the Flying Scotsman.....
Again, thanks for the encouragement and advise (to many to mention here) I will take more pictures at the weekend to bore you all with.
I shall also be compiling a list of parts, which will be a long one me thinks.
All the best,
The Baron
