Master cylinder not level. Correct level?
Gentlemen,
I'm going to be replacing the master brake cylinder on my '79 F250 because it leaks. While I'm at it, I was wondering - when the truck is sitting on perfectly level ground, the master cylinder is at quite an angle to level. The front end points way up. It's probably at a good ~15 ~ 20 degrees to horizontal. This makes filling to x-inches from the top a rather subjective thing, as there is about 3/8" difference in fluid level from font to back of the larger reservoir.
Looking at the power booster, I see that the flange between the booster and the firewall is the culprit - the flange is actualy angled as if to intentionally create this angle. It's not bent - it's made like that.
But this seems odd to me. Is this supposed to be like this?
I've found many non-conforming parts on this truck - some past owner wasn't very particular about the parts he put on this thing. So, if it's not supposed to be like this, I wouldn't be surprised if it was a replacement booster from something that was supposed to have an angled mounting flange,
Thanks.

I have a 77 F15, and my mastercylinder is set up the same way....I also had a totally stock 78 f150, second owner, and it was the same. I don't know why they set it up this way, but it seems all of the older fords are this way...
Someone please correct me if I'm wrong on this....

As lons as there is enough fluid in the reservoir so that when the brakes are actuated the level doesn't get below bottom of it, it doesn't really matter.
I would also think the rear reservoir being the Primary source of fluid that since this one gets full,that's okay

Do those who brake softly need help? I was just speculating as to why they are not level.
Perhaps their thought was, If the MC was mounted level and you braked hard it could slosh away from the hole in the resivor(sp?) ...especially if the fluid level gets low due to the brake wear.
