TR-3 - Response to disk brake advice

[John Cowan <jfcowan@sj.znet.com>]

Thanks to all who sent advice.  Some info:
1. Most wrote in support of DOT5 silicone brake fluid.
2. Many suggested I check for constricted brake hoses.  I will, but they
were put on just last year during a partial brake overhaul.
3. Others also suggested checking brake master cylinder adjustment.  Will
do, although the problem doesn't show up on the rear/drum brakes - on the
other hand, I think they have return springs.
4. Others questioned my mechanic's judgement.  I trust him, even if his
conjecture here is wrong, since I didn't pay him to take things apart and
inspect.  He suggested I take a complaint to the guy who did the original
work, which I will.  He also said that silicone was a controversial issue.
5. One respondent mentioned a check valve on Tr-3s and 4s.  I'm not
familiar with it and will follow up with him.
So ...... Plenty of leads to follow up.  Isn't that how it often is?
