Needing help badly, frount brake locked on

[ben]

hey smartalec. looks like you have had some fun!!

heres my 2cents

$180 shpould get your booster recoed to new. $60 for a second hand not leaking one from me if i have one kicking around which i should.

if i were in your situation with the wheel cylinder i would pull it out wash it clean in brake fluid get some wet and dry 800 or something and scratch all the rust off the inside of the wheel cylinder have a good look at the rubber put it all back together and it should get you out of trouble for a few weeks.

i would be more inclined to get your old ones resleaved stainless steel (wont rust ever again) if you are planning on staying drums. its cheaper and better. and ofcourse new rubbers which are a standard rubber pretty sure.

going disc is a bit of stuffing around and its not something id do in a hurry. (or should do in a hurry) plus you need to get new rims too,

cheers

well im convinced to stay with drum then..lol

now where an i get the rubbers an that for the cylinders.. or there different types?
what type of cylinders do i ask for at the auto shop?

the boster has waited 2yrs so far.. so a bit longer wont matter..

[hunterbynature]

take the old cylinder with you to get matched up, do you have bnt over there

[Kav]

i have replaced front drum cylinders, abs brakes had them listed and only took overnight to get them in
i think there were two bore sizes listed so take it off and take it in to them, so they can measure it and get the right one, or the right seals if you are going to clean it up yourself
abs wont be the only one but you'll have better luck at a brake specialist than somewhere like stupercheap

[Smartalec]

what sort of prices am i looking at?

[Kav]

i cant remember the price but i do recall being happy with it

rubber seals wont be much. a bloke gave me a set last time i wanted some:)

[Smartalec]

so mine are leaking out of both...
do i need to get rubber seals an hope that fix's it for the time being..

or order a couple of new cylinders to go in it.

i like the rubber seals idea if it will fix it (sounds cheap)

[ben]

make sure you clean up the inside of the cylinders first. depends on how bad they are.. photos??

[Kav]

as the seals start to deteriorate, water and dirt get inside the brake cylinder, rust and dirt builds up destroying the seal more and making an uneven surface that the seal can't seal against.
eventually this crap builds up so much that when the piston pushes out, it gets stuck and won't come back in causing the symptoms you have described
as ben said earlier you can clean it out and smooth it back with fine wet n dry so a seal will work again, but chances are if it has gone to the point of getting stuck, it is quite corroded and may takes a lot of work to make it good again
i have, in order of worst to best
1. when stuck out bush, done them with fine paper wrapped around my finger, probably causing an uneven surface, and put the old seals back in, that only just got me out of trouble

2. with access to tools but not much money, turned a piece of broom handle on  a lathe to just smaller than the cylinder bore, wrapped it in piece of flannelet shirt, smothered it in grinding paste, and spun it in a drill inside the bore, producing excellent results, fine smooth even honing.  put new seals in

3. with money and limited time, take it to the brake place and buy new ones

no. 3 was my favourite and safest method of dealing with this type of problem
it all depends on budget and your level of ability to d.i.y
thats a fine looking van you have, it would be a shame to put a ding in it
