MK2 VW Full Brake Rebuild, Rear Disc Conversion Walkthrough and Proportioning Valve Explained 

Love your style and sense of humour. Yes, I'm British as you can probably tell by the spelling. Keep up with the filming, it's helping me get motivated to do my Mk2 GTI 8v.

I absolutely appreciate the explanations of the brake bias and proportioning valve. Makes total sense with your explanation and diagrams.

She done got some stoppers now. Good job there baked bean

Amazing stuff man! Got a 86 GTI sitting in a garage feeling real lonely for maybe 5-6 years now. Want to jump on it and do things soon. This really helps the motivation and the “you can do it” vibes!

Thank you for posting another entertaining, yet informative video. We greatly look forward to your future renderings.

excellent stuff yet again. i've done a similar brake conversion but with g60 golf bits. having watched this video i now realize i have not adjusted the intrusion on the new bigger brake booster nor did i know about the adjustability of the mechanical brake light switch. gonna have to revisit those areas. can't wait for more :)

Brakes? Who needs 'em?

I think what you have is what we call old style disc brakes in europe handbrake cable on top vs new cable below the beam. I used mk3 GT stubs on my 91 mk2, mk2 discs and pads and mk4 calibers. mk4 calibers because i had read that they were better due to them being aluminium but almost identical to the normal mk2/3 ones. Anyway the newer mk2's with rear discs as far as i can gather has the handbrake cable on the bottom pulling down, and the brake line is on top. So it only needed minor bending of the brake line a b5 passat brake hose because of mk4 caliber, again i read that was best. and thankfully i got the right handbrake cable in my first try. Only issue is that they are a pain to bleed probs because of the proportioning valve

It seems like your return spring on the rear brake compensator is shot? The valve looks like it's floppy to me. The bottom the of the valve, where the "hex" adjustment is, should be pushed outwards. The main spring pulls the top lever of the valve, compressing the lower portion. There's a small return spring that opposes the force
