E28 520i 1985
I replaced my rear drum brake SHOES and all went well ... but when doing
a hard braking test, only the front wheels lock up.
Is this normal? Of course I should have done a before and after test and
now I can't remember, but they did seem to be better before (but
squealy- have replaced front pads and discs too). I did bed them in for
a few mins driving with brakes on down hill.
I did test the brakes with each wheel jacked up, so I know they do work
My real question is about the "thermo adjuster" which (somehow) turns
the adjuster nut and makes the shoes more in contact with the drums. My
Hanes manual said to back these off to minimum before reassembling. Is
this right? Wouldn't it make more sense to adjust them to "nearly
touching" the drums- or does the "thermo adjuster" do that (by magic)
Yes, it is normal. In fact it is *preferable*. If your front wheels
lock, you can't steer, but you slide straight ahead. If your rear
wheels lock up, you spin the car and slide rear end first.

no, it's a 1985
anyway the rear shoes seem fine now- BUT the front discs are squealing.
I recently replaced the pads, and the discs about 6 months ago cause
they were vibrating through the pedal when braking from 60 mph.
That problem has developed again, luckily there are some excellent
websites on the subject, such as...
ya gotta keep yer greasy fingers orf the brake bits
in the absence of ABS...
Yes but if the front wheels lock and it slides, you can ease off and quickly
regain control [and probably miss the wall]. OTOH if the back wheels lock
and it spins, then you are almost certainly going to hit something.
