Rear Brake Caliper

Finally finished the rear brake caliper bracket.
I an using a Honda Varadero 125 Rear wheel
so the bracket and caliper are matching.
There is an extra wedge shape welded to the
bottom to match up with the Yamaha YZF-R125
swingarm.

Stainless Line

Thought i would post up some images of the rear brake setup with the new braided HEL line.

R Caliper rebuild

After an initial coat of primer, 3 coats of red and 3 coats of clear lacquer the rebuild of the rear caliper is finished. New seals and pads are added after a full clean out of the internals and pistons.
The mounting bracket has also been cleaned up, polished and coated with ACF50. The bolts, washers and lock nut have also been replaced with Stainless Steel units. The threads have been coated with CRC SP400 corosion inhibitor and finally torqued ready to go.

Here is a quick link back to the original state of the Caliper >

Rear Caliper Masking

Before masking off the joining surfaces of the 2 halves I decided to check out the pistons to make sure they were still ok . . .and sure enough with aid of an old brake line and a bicycle pump the pistons popped out and they are great, no rust or marks on the surfaces and the internals of the caliper are like new, great I can now go ahead and recover the caliper in the original bright red finish.

Rear Caliper breakdown

Following on from the post below http://2strokelover.blogspot.com/2012/01/rear-caliper.html I attacked the rear caliper with the Dremil and stainless steel wire brush. I took roughly 90 minutes to remove all the paint and oxidization. I had to use some 220 grade wet and dry sand paper to get into the deeper crevices.

Rear Caliper

While concentrating on the rear section of the bike in preperation of the rebuild I attacked the rear brake system. I managed to release the 2 M8 bolts holding it together. The piston dust seals are totally perished and need replacing.
The exterior of the caliper is in bad shape too, again a lot of corrosion and paint loss.
