- On this installment of the 1.8t MK2 GTI (re)build, I rebuild all of the brakes and convert the donor shell to GTI rear disc brakes. Also covered is the proportioning valve and brake bias.

Thank you for your inattention. - Auta a dopravní prostředky
good to know the calipers are the same, I wanted vented discs on my 86 turbo diesel
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 :)
Thanks! Usually they don't need adjusted, but it's definitely worth checking, my last mk2's brakes dragged until I figured that out.
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
Btw i have now made it to the master part had no idea the booster could be adjusted i tried a bigger master i had laying around because i plan on putting "big" brakes on the front as well when i get to it. And the brakes were always on gotta remember that for when i get to it again
Brakes? Who needs 'em?
👍🏻
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
There's only two little coil springs in there that work against brake pressure, plus the adjuster is still loose. There's no tension on the lever until I hit the brakes. Not saying it's correct, but it's always been like that and I never had any issues with the rears.
@@bakedbeansgarage116 there needs to be tension for it to return correctly if you want proper function. As long as you’re not locking the rears first then not a big issue but not optimal either. I’ll send you a vid on fb something this week showing you what I mean
