Oh No Captain!!!! We've Lost Hydrolic Pressure!!! AAAAAAHHHH

found out why my pedal pressure was low and why my pass rear and drivers front were locking up at end pedal travel.

Ok first off, VW brake system overview for MK1


Master Cyl

x1====x2
|
-------------- resevior partition
|
y1====y2
|
|

x1= drivers side front
x2= pass side rear
y1=drivers side rear
y2=pass side front

now, some dorkwad who inspected the car in ohio clipped the drivers rear line with the edge of the car lift as the line runs pretty close to the lifting point. This put a pinhole leak in the line, not enough to drip from sitting but enough to drip under load. So what would happen is that fluid would go byebye until the rear portion of the resevior would go go dry. This caused the brake system to act just as it should in this sort of situation and apply pressure only to the drivers front and pass rear at the end of pedal travel.

Goin to napa today to get a roll of 3/16'' line and going to cut and flare me a new drivers rear line. yay. Hopefully Ill be done by this weekend and tearing around VA with it, the weathers been killin me with all this rain. :evil:

good diagnosis...

thats kinda cool that it automatically splits up the braking like that. at least they didnt go out entirely, i'd cry for you if that rabbit went into a ditch after losing the brakes 2 weeks into your ownership......

All master cyl do this, and we can see why. Older systems used to be split front/rear, but people spun out when they braked after losing half of their system, thus todayÔÇÖs diagonal split.

"i see," said the blind man, as he peed into the wind, "it's all coming back to me now."

But it did make for a fun time tapping the brakes while going into a straight line and getting sideways :lol:
