I drive an 82 rabbit pickup gasser without power steering or power
brakes. The weather has turned cold here lately, and my brakes have
all but given out. The dummy light it on and the brake pedal nearly
goes to the floor. When I am driving on snow pack, the front left
wheel locks up easily, while the rest just roll. I topped off the
fluid reservior with no result. I noticed that the snow around the
rear left tire was an orange color, with the snow melted under the
tire. The liquid is odorless. This had happed once before this winter
over a cold snap. Since the weather got cold again at the same time
this problem reappeared, I know it is related to the cold. Can water
get into the calipers or wheel cylinders and screw something up? When
I changed the front pads this summer, I noticed that the rubber boot on
the piston of the left caliper was coming loose. I did my best to put
it back in. The O-ring was fine tho. I am a student and do not have
much money at this time. Any advice? Thank you. |

sounds like time to pull the rear drums and check/replace the wheels
cylinders and shoes.
You got a brake fluid leak.

do the brake cylinders fail more often than calipers? How tough is it
to do the rears? Also, how do I flush the fluid and replace with new
stuff? I have never done it and the fluid in this trucks is probably
decades old. >> Stay informed about: brake problem, vw rabbit |

You need to haunt the local used bookstores and pick up one of each:
- Bentley
- Haynes
- 'Poor Richard's How to keep you Rabbit, Jetta, Scirocco.... Alive'
Having these (and friends who will fix your car for pizza and beer) is
what you need.
Flushing (and bleeding out air bubbles) is done Rear Corner farthest
from the Master Cylinder, then the other Rear, then the Front Corner
farthest from the M/C, then the one nearest.
Use a good DOT3 or DOT4 fluid; a complete flush can usually be done
with one large bottle and a small one to top off with at the end.
(Keeping opened bottles around is frowned upon because the brake fluid
tends to absorb moisture from the atmosphere.)
Don't get confused by the different types; DOT5 and DOT5.1, one is
synthetic but usable, the other is Silicon and is indicated for racing
and dedicated systems made for its use. The synthetic juice can be used
in normal systems though.
hth,

I got a Bentley, but the troubleshooting section was not very helpful
for my situation? What do you think would cause the problems as
described in the first post? A local guy thinks that the front right
caliper is bad and should be replaced. His reason is the fact that
that wheel is the only one that can stop or lock up. He says that
leaking fluid will make that brake sticky and allow air into the
system. Could the master cylinder cause an intermittent problem
related to temperature? Can water freeze in the brake lines and cause
this? >> Stay informed about: brake problem, vw rabbit |

Yep, yep. You got air in the system somewhere, that is very likely. As
for seals leaking enough to have allowed the system to 'sip' air, that
remains to be seen.
What's really important is that you bleed the system. Avoid pressing
the pedal all the way to the firewall, as this tends to scrape
previously unused portions of the M/C with the o-rings in there;
causing premature wear.

Fix the current brake problem with the wheel cylinder before spending more
money? It's not hard to do since you got a manual, but a few tips are to
soak the metal brake lines first so you don't bust them off. I use PB
Blaster! As far as tools:
5mm allen wrench
11mm brake line wrench. If you can't find a 11mm then 7/16 works well.

yeah, I just contacted a local shop. Im getting the master cylinder
replaced tomarrow. Funny thing happened yesterday. While I was
cautious driving home, the brake problem in which only one wheels stops
suddenly cleared up. The braking seemed completely fine. It seems
that the master cylinder is intermittent and scary as heck. Yes, that
also means that the righ front caliper was doing its job again. It has
to be the master cylinder doesnt it? I hate to fix something that aint
broke. >> Stay informed about: brake problem, vw rabbit |

wow, the shop undercharged me big time. They changed the master
cylinder, the brake cylinders, brake shoes, and a brake line for $235.
That included the cost of the master cylinder only. I thought that it
would be about $400. I dont feel bad tho. They overcharged me last
time for changing the fuel pump. That cost $350, and the fuel pump was
on the outside of the tank, so the tank didnt need to be dropped.
