Rear caliper leaking around 'block off' plate ..

[Saul]

Anyone got a fix for this? The caliper is leaking around the emergency brake block off plate. Brakes won't hold pressure because of it.

Should I try using some kinda gasket sealer material there?

No Saul, there is 1 or 2 seals in the caliper housing that need replaced.
The pin for the piston, is what is leaking.There is a o ring seal or 2 that seal the piston shaft.
Gotta rebuild all the caliper seals now.
If you look at the parts schematic online you will see what you need.

You were 100% correct. It had come dislodged. Put it back in lace and all is fine now.
