Brake line questions

[Phil Rose]

One of the rare times I agree with Bernie (when he chants his DFWAB mantra).

If your "sticky" caliper symptom is that the rear brakes are wearing 
the pads unevenly and/or won't run free when you release the hand 
brake...then the first place I'd consider "fixing" (i.e.,  replacing) 
is the hand brake cables--especially if they're original or more than 
5 or 6 years old. But if you can determine that the cables are good 
and are not the source of the "sticking", then you do have an 
internal caliper problem which requires caliper disassembly and 
overhaul.

I've done it and it's a bear of a job just to manipulate the internal 
parts and re-assemble correctly (and if you can get the needed 
parts--including a new "oil" seal for the shaft of the handbrake 
lever). [hint: NAPA p/n 6405 (16x24x7) from Chicago Rawhide]. 
Corrosion of the HB lever shaft is generally at the root of sticking 
rear calipers. So a good cleaning up with fine emory cloth will 
probably be needed.

Of course Bernie might scratch his head and respond "Corrosion? Never 
heard of that. How does that happen?"

My usual response is, "Easy. Just live somewhere other than Nevada." ;-)

P.S. If you don't enjoy doing this kind of thing  and/or have 
something better to do with the time (perhaps a few hours per caliper 
to rebuild); you might consider buying rebuilt calipers. Of course 
that's somewhat of a crapshoot, too, depending on source.
