so i am finishing up my toyota axle swap and have a problem i dont quite understand. I Installed a early 80s firebird master cylinder to increase my braking volume as i am running 4 wheel discs on the yota axles (btw this is on a samurai), so anyways bleed through everything fine and have a very stiff pedal but very little for brakes. The pedal seems almost too stiff ive never had this problem before.

any ideas?

Are all the calipers free and the wheels rotating correctly, if so then the m/c is too big.

no when i do brake it will stop but is slow and weak.

did you remember to hook up your brake booster?

i never messed with the brake booster the just unbolted the stock sammy M/C and bolted on the flaming chicken one. the seal between the M/C and the booster does not seal the greatest could that be the problem.

dont you have to change the length of the pushrod when you do a MC upgrade?

from all the write up i have read on the swap no

still cant figure this one out i checked my booster and its fine. the pedal barely goes down at all even when the truck is off im stumped?

would the pedal go to the floor when bleeding?

yes it would

have a look and make sure your caliper sliders slide, a guy over on the grand vitara forum had the same problem, it ended up being both his caliper sliders where solid lol

didnt even think of that and the axles i just stuck under my samuarai were sitting for about a year so thats a definate possibility.
