Customs Will I be injured in a crash if I do this?

    Is it okay to run a master cylinder not quite level. Talking about having the outlet end maybe 3/4 of an inch higher than the plunger end? Reservoir will be remote with a hose to the cylinder so it can be mounted level.[​IMG]

  2. I have no way of knowing of you will be hurt in a crash or not. As far as tilting your master a little bit Wilwood should be able to answer that.

    I've seen modern cars with the MC at a slight angle of approx. 15 degrees. So I don't think it matters.

  4. I have seen a lot firewall master slightly at and angle. In your case maybe you can fab up a push rod with a bit of a Z in it?
    Def ask the manufacturer

    who’s to say if will you be injured in a crash? A lot of things need to happen or break. Or just another crappy driver.

    Why not make a wedge to make it level?

    It's a clearance issue. Hard to explain.

  7. Is remote reservoir going to be level or close?

    If I recall correctly the late mustang is not level, I was looking at the master for the Fairlane ended up with a 67 Corvette.
     
  9. If you run the remote reservoir a few degrees won't hurt. In fact, the air will go to the high end right where the bleeder is. No sweat.

    It can be mounted vertically if it is bled first.

    Regarding you being injured in a crash? You'll have to crash first, then you'll know.

    A lot of OEM have unlevel master cylinders. I never liked that, as I was accustom to the cylinder being level. If OEM does it , it should be good.

    i always thought they are not supposed to be level, but with the outlet higher to bleed the air out

    Not unless you forget to fill it.

    Look at motorcycles.

    no way they are level in a nose hi gasser, or a 70's jacked up car.

    The amount of fluid in the reservoir will be different, but the pumping power remains the same.

    I've driven up some pretty steep hills and my brakes never quit working.

    I am not sure what car you are mounting it to. The master cylinder may sit more level than the picture shows due to the rake of the car.

  19. GM used to have the master on pickups mounted at a crazy angle. No problem

  20. Before designing a brake system I would suggest learning how the various components work. That will answer all the questions without having to believe random strangers

    I cut the end off it leveling the image but this is the angle that the mc on the Cad DTS that I used to have would have with the cap on the reservoir level.

    It doesn't matter much if any on the angle of the piston as long as the reservoir is able to hold enough fluid.

    In order for the piston to move freely through the cylinder bore pressure has to be applied to the center of the piston evenly throughout the pedal travel. Whether the amount of tilt you need in order to solve your clearance problem is enough to change that geometry I don't know. If for example the angle was drastic, say 45 degrees, then you could easily see that as well as pushing forward, the rod would be effectively pushing the piston downward. This would cause the lip on the bottom of the piston cup to collapse a little and maybe lose enough pressure at the top to not effectively compress the fluid. At minimum the added friction would make for a less smooth brake action. Relocating the pushrod to pedal attaching point would be the remedy were that the case.

    I see 5/8 on the side of the master, is that the bore size? If it is that’s really small.
     
  24. Yep - GM did it for years on trucks and cars - think about 1973 was the first in like Nova's and such....

    There is not supposed to be any air in the brake system, the hydraulics won't care what angle they work on, as long as the fluid reservoir maintains enough fluid to keep the ports of the master supplied with fluid.

    As far as being injured in a crash, I'm not privileged to know that information, and if I was, I probably wouldn't have permission to tell you.
    Would you really want to know ahead of time anyway? Gene
