Hello Group -
I have been having consistent problems with the right front brake
dragging, grabbing and overheating on my 1957 300C for over two
years. Virtually ALL brake components are either NEW (master
cylinder, flexible lines, wheel cylinders, brake shoes, fluid) or
thoroughly refurbished (drums). Even after meticulously adjusting
the brakes, after driving for barely 1/4 mile, after applying the
brakes from only 35 mph, the RF shoe(s) apparently do not pull
back fully when pedal is released: the car pulls violently to the right when
brakes are applied - a full lane change and nearly yanking the
steering wheel from my hands! There is no evidence of fluid
leakage anywhere, so I don't suspect a wet brake lining, although
I have not yet taken the drum off to inspect. I suspect a broken
or weak return spring (maybe plural) is to blame, although
everything looked fine when reassembled a couple years (and barely
200 miles) ago. Clear evidence: After driving only five miles
at highway speed and only two gentle brake applications (turns to
get onto highway), I coasted to a stop on the shoulder and checked
brake drum temperature through the wire wheels with an IR temp
gun. All three other drums showed ~110 degrees (90 degrees
ambient temp), while the RF drum was 220 degrees - it must be
dragging!
I want to be prepared to replace those two RF springs when I take the car in for that brake service. The only springs I can find are from Andy Burnbaum for $96/set of 8 for front and rear brakes; the rear brakes (and LF brake) work fine, so I don't need those extra springs unless I have to. Does anyone have a PAIR of new or known good return springs for the FRONT brakes on my "C", and how much do you want for them?
Related question: I've seen some conflicting advice on how those front return springs attach to the shoe: some say the hook on the spring should go to the"loop", while others say it should go to the nearby "hole" to get a more straight-back pull, whereas hooking to the "loop" might induce a "cocking" effect and increased drag as the shoe slides between the plates when withdrawn. What is the experience and collective wisdom among you?
Any other ideas about what could be causing my problem?
This radical "pull" is dangerous and drastically limits my driving, so I really need to fix this once and for all!
