    NEW BRAKES....DOT 5?

    I run DOT 5 in my disc/drum system and it works great so far (years). I did find the hard way that it gets past the seals in my Howe clutch slave (pull) cylinder... rebuilt the slave, flushed the master and line, and now that master has DOT 4. The urban legend that bad things will happen if you...

    Removing push rod from MC

    "There are very few personal problems that can't be solved with a suitable application of high explosives"... But try a pry bar and a vise first :)

    Disc brake hoses don't fit frame brackets. Grind which one?

    I took a closer look today... the snout of the hose will go through the bracket if held at exactly the right angle. But the part that keeps it from rotating in the bracket is definitely different between the drum brake hoses (round with a flat on one side) and the disc brake hoses (hex with one...

    Disc brake hoses don't fit frame brackets. Grind which one?

    Thanks, I think I'll do that (my concern was weakening the end and a potential stress crack when the flare nut is tightened and under pressure with heavy braking)... Also I will carefully inspect the bracket to make sure it's not twisted. I looked at many pics online from different suppliers...

    Disc brake hoses don't fit frame brackets. Grind which one?

    I just got new front brake hoses for my '72 Dart which now has '73-up disc brakes. I did request hoses for a '73 and they fit the calipers & banjo bolts, clear the suspension, etc. But the chassis end of the hoses won't go through the mounting tabs so I can install the retaining clips...

    Where to route rear brake line?

    I'm finally working on my '72 big-block Dart again. I originally got the car as a rolling shell so it had no brake lines at all. Now it has an aluminum 2-bolt master cyl. with adapter, '73-up front discs, and 10" drums on the 8-3/4 rear. I am fabricating all hard lines. The front is fairly...

    Master Cylinder question.

    Hang on a minute... it's the other way round! If through the pedal leverage you have 700 lb of force to apply to the m/c piston, if it has 1 sq in there is 700 psi generated. OK so far. But if you are applying 700 lb to a 2 sq in piston that is only 350 psi generated... pounds PER square...

    Master Cylinder question.

    Six years since the last post... got to be some kind of record :D While we're here though, Autozone and others show the manual m/c has a 1-1/16" bore but the power m/c is 15/16"? Would have thought it'd be the other way round, but that seems to be consistent over several store sites. So...
