locked brake caliper - spooge hole cleaning

[CatatonicBug]

I cleaned rear master cylinder and front and rear calipers that operate off them. I got rubber kits for rear mc. found the dust cover for rear was much oversized and oring was hardened. this freed it up. still dont have dust rings on front but seem to be fine. Probably would be better if had front rings to keep out moisture but kits are around 20 apiece and trying to get by without it. The corrosion was also between outer dust ring on front and outside of caliper but might not have interfered. The hardened oring putting too much pressure on piston seemed to be biggest problem.

There is no dust ring on the fronts for the XJ calipers. I have a rebuild kit, and it does not include that. They have 2 o-rings in the caliper bore instead.

That outer o-ring performs the same function as a 'dust seal', just not quite as well. It's there to protect the inner seal and the bore...
