I plan to put a pressure gauge on this week, how many pounds should I be looking for? Could new master cylinder be the culprit?

my little 5 foot 1 inch beautiful bride Beth pumps hers up to 800 psi on the starting line before engaging the two step and that's with her itty bitty size 6 feet
bobby we have some much better pads for you. same as what we put on Beth's car

600lb up front after pumping the hell out of it. Gonna try smaller master cylinder before I start trying to take this brake pedal apart.

Bobby,

I used maximum motorsports manual brake conversion kit ($199 List price) with all stock components on my Super Stocker, brakes just fine and I foot brake it too sometimes. Brake pressures (just went out to garage to check) easy push on pedal 600-800 psi, med push 1200-1400 big push 1700psi+. I love the quality of the components and Its a nice textured pedal.
Here's a link below. I syringe bleed the master backward to remove all air. Stock front t brakes, 10" ranger rears.

Ok thank you for the tip. Getting the brake pedal out was a nightmare so I stopped and put it back in and decided to get a Ford Ranger master cylinder to see if that can get me to at least 800psi. If that doesn't work then I will look into that new pedal kit from MMS.

Ok got the car running again and installed the MMS brake pedal kit with better ratio so I can hold around 2300rpms on the line as opposed to the 1800 before. This is with the '86 ranger master cylinder. When I try the two step any higher than 2300 it creeps through the beam. My lights suck and I have 20lbs of air in the bias ply slicks. Need to raise launch rpm to reel the RT in. Turning 1.60-1.62 sixty foot times when not creeping. In order to hold better on the line, should I upgrade the back to a disc setup from the drum setup or should I upgrade the front to a bigger/better disc setup than the current stock configuration?

How low is the first gear in your trans and what about rear-end ratio?

A really low first gear ratio can cause the lower stall rpm.

2.92 and 4.88 with 28" goodyear slick

Bobby,

I have stock 89 brakes in front and 10" ranger brakes in the rear. Works great w/footbrake with that MM manual brake kit and stock master.
