914 brake question Options

[honlude]

Hello

i am working on my 1975 914 1.8 , i rebuilt the master cyl , rebuilt right rear caliper , and replaced left rear caliper , replace the grommets on master cyl for resov. lines , i have set the rear brake venting to .008 and bleed the system multiple time , i have no air coming thru system at all , i have brakes now but they just dont seem to be correct , if i stand on the brakes hard they do not lock up while driving, are the brakes on these just that way or dose anyone have any other suggestions on what could be a problem , ... i have no leaks anywhere either and the park brake seems to hold the car under a light load

thanks craig

I have no doubt that you still have air in your lines. A stock system should have a nice firm pedal. You should definitely be able to lock up the tires with any pads. I find on most 914s that I have to bleed, drive, bleed, drive, bleed some more. It's a MAJOR PITA! But something about getting the car out and using the brakes frees up more bubbles. BTW, I'm not talking about a long drive here. Just up and down the block. BE SAFE!

Did you bench bleed the M/C before you installed it? The M/C is a PITA to get all of the air out of. The Prop Valve is a PITA to get all of the air out of. You're not clear yet. Search for posts describing the long tube bleeding method. There is one by Trekkor and I think SirAndy has one in his 3.6 build thread.

Anyone who disses the stock system* has not had a completely correct system.

*motors larger than stock, or cars used on a large racetrack can complain about the stock system.
