I'm pretty clueless. That's why I come here for help, and I appreciate the
assistance I get from the nice people here. But, hey, at least I don't feel
the need to tear people apart with sarcasm, right? Peace to you.

If he's going to keep the car, get it fixed, **ASAP** and keep the car
off the road untill it is repaired. If your ex won't pay for it, pay
for it yourself (ASSuming that your son doesn't have the funds to pay
for the job himself).

IIRC, one of the purposes of dual systems is incase one system fails
while in motion (such as suddenly developing a leak and losing all
fluid on that side) you still have *some* braking available to bring
the car safely to a stop. You say that the rears are not working and
fronts are. Don't wait for the fronts to fail and an accident to
occur. GET IT FIXED!

Oh, and for the love of Allah, pay no mind to what that idiot,
"Speeders & Drunk Drivers Are MURDERERS," said.

You aren't really this dumb, are you?

Even oil-soaked shoes will provide SOME friction.

Enough to hold the car? I have no idea. Best not to test the
condition empirically, methinks.

Well for starters there will be TWO rear wheel cylinders, one one each side.

Do they mean just one side was faulty ?

It's not really hard to fix this as a DIY job quite frankly if you have any
reasonable level of practical skills. The bits won't be that expensive.

That's exactly what happens. The friction material loses its friction when
saturated with brake fluid. It is an oil of sorts after all !

Why would you expect the average woman to know how car brakes work ?

Re. idiot light, the complete situation was that the car was leaking brake
fluid. They brought it into the shop and found there was a leak in the brake
line in the front of the car, which they repaired. That stopped the leak and
stopped the light from coming on.

Right now there's no light that's coming on, just some fluid leaking out of
the rear wheel cylinders into the drums. But not enough for the light to go
on.

Considering the mass of the Golf, and the quality of the handbrake
system, it's not a given that the handbrake won't work.

Considering many parking brakes are marginal to begin with, leaking
brake fluid could easily make them next to useless. I ran my Jeep, which
had a leaking axle seal at the time, through the brake tester at work,
and on that wheel I had half the brake force compared the the other
wheel. I know differential oil has different characteristics, but still...

It would depend on the design of the back plate and drum I would guess.
The wheel cylinder that went on me last year was discovered in part by
'what's that puddle'. The shoes never got any brake fluid on them. It
just went along the back plate through the over lap with the drum and
down to the ground.

I would think it possible for the parking brake to slip because of
contamination, but it would be unlikely IMO... then again the car may
have a drum brake design that any leaking brake fluid goes on to the
shoes.

Per the message I post in a new thread ("Driving With Two Brakes - Part
Two"), it was actually $130 they quoted, and it was ONLY for the wheel
cylinders. They say they're not going to replace the brake shoes, but only
clean them (even though there's brake fluid on the outside of the brake
cylinder).
