3 Questions resulting from a beautiful Sunday afternoon of Westy tinkering:

1.  Speedometer:  My speedo reads roughly twenty to thirty mph above real
speed.  I've lubed the cable at both ends, jiggled it around, and did
everything short of replacing it.  Is there anyway to calibrate the speedo;
or do I need a new cable?

2.  Headlights:  My headlights are far too dim for safe operation.  I
figure this must have something to do with a loose ground or bad connection
somewhere--also know that my front light turn singnal bulb socket has iffy
connections--any other ideas on increasing brightness?

3.  Brakes:  When parked, pressure on the break peddle maintains a strong
"grip."  When moving, however, the peddle sinks to the floor under constant
presure...and occasionally, a high pitched whining sound (like escaping
air) comes from the direction of the master cylinder:  Please, somebody
tell me I don't need a new M.C.....

Thanks in advance for any advice,
