Hey guys !

Been working on my brakes for the past few weeks....kinda went on me 2 weeks ago.

Had to change my MC and most of my back lines. My Brake Proportioning Valve is seized and I can't even get 3 out of the 4 lines off and it looks like a ball of rust. Was told it should be changed.

any suggestions on parts in the GTA

I went to a place called Frisco and got a quote of 130ish

while I have most of my system apart, any suggestions on anything else I should change ?

oh yeah ! I kinda have no choice

the PO changed the half of em, but the other ones are nasty and broke when I removed the Brake Proportioning Valve.

gotta love rust.

Problem is they don't carry the proportioning valve. What I did is go to http://www.altrom.com/models.jsp?makeId=421, click on your vehicle model, then "brakes control" along the left. That should give you a page that has a "pressure regulator valve" like http://www.altrom.com/partdetails.jsp?id=1118. Then at the top of the page, click the tab for find a retailer, enter your postal code, and you'll know where to spend your money. I paid $137 with taxes at Partsource. If you have a bit of time, you may find one cheaper on eBay, but I don't know how much you'd save by the time you pay shipping, exchange and duty. http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=260237853359
My original was so rusty that the 10 mm nuts on the ends of the brake lines were small enough to let a 9 mm wrench slip over the hex. I ripped it all out and replaced it. Got to love salt on the roads in the winter.

What car and what country, eh?

Arizonaautohaus in Phoenix, I think has them for $100 for Mk. II Jettas (can't remember......). I needed one last year.

For an '86 Jetta: $70.29 for Obama bucks.........

Cool stuff guys !

did some searching lastnight and found a place for 110.00 plus tax local to me.

thanks for the feedback I have a good idea as to what I should be paying in CDN dollars.

a little off topic here, but has anyone experimented with coatings for brake lines/parts to inhibit rust? i was thinking of an epoxy coat for brake lines... good idea? bad?

i was also thinking about one of those electronic rust inhibiters... since the brake lines are grounded

A guy I work with has one of the electronic rust control things on his car. Not sure if they really work since his car is just 3 or 4 years old. Mind you it is cavalier :twisted:

Its funny you mentioned coating the lines. I was thinking the same thing after I'm done with installing my new lines.

I picked up a can of Rust check undercoating for when I replaced my driver’s side floor. I used that and the spreading foam to fill the minor gaps and to protect the area around that I cut out. Oh and about 6 things of roofing tar... that’s another story.

back to my original point about the rust check stuff. It puts a nice thin coat that bonded well to the under side. I took the time to do the lines that where replaced already and it seems to do the trick. Time will tell if it really helps.

i've wondered if anything will really stick to brake lines properly, as they can get a bit hot at times... i figured why not (just before installing them - AFTER bending them to the right shape) dip them in some kind of sealant/paint, or even powder coat them? bullet proof brake lines would be kick ass up here in Canada :wink:

You can get brake lines with great coatings on them.
