Non-power brakes?

[jaed_43725]

Excellent article. I am going to check out or replace the wiring.

Solved the hard brakes problem. Had 2 small oil leaks and when it gets low on oil as we all know the vacuum pump suffers. Fixed the leaks, now just have to wait till morning to make sure its full and brakes will be working great.

I replaced the low side oil pressure sensor, but this did not fix the annoying buzzer. Still have to do the wiring.

I guess I didnt totally solve it. Initial braking is fine. But the 2nd pump is stiff. I am getting plenty of oil. I will replace the check valve, check the vacuum pump again, and have the booster checked over. Could be that the booster has fluid in it.

Did you try T in a vacuum gauge and observe vacuum levels while you drive?

That tee and a gauge is the way I would go.  When you get cars this old, one possibility would be a crack in the booster diaphragm that allows vacuum to build and hold when the pedal is not applied, but then as you apply it, the leak starts.   One possibility why the first application is powered but the second is not.

92: I do not have the equipment to do that right now. I will look into it though.

clbanman: I am going to replace that check valve and probably the brake booster at some point.

Put on bigger brakes, (g60/gti/vr6) and you can use the old brake master without powerbooster. The bigger brakes has a larger cylinder, which means that with the small cylinder master you will get the wanted effect. :-)

Big brakes with powerboosted small master will feel squishy...

I'm pretty much as big as I can go. Any bigger and I would need larger rims. And larger rims won't fit without issue.

I've had 9x16" et15 rims on my Golf, would fit on any mk2:-)

7.5x17" et37 fits also... without issue other than looks...
6x15" et35 is original G60 rims, will fit over G60 brakes and not look like a donk:-)

Perhaps I will fix what is wrong first. Then go to braided stainless steel lines, then eventually the bigger brakes.
