Hey guys, reaching out for some help here.
I have a 66 Mustang, I did a CSRP power front disk conversion a while back and I'm finally on the road.
I'm having some braking issues, and was hoping someone may have some direction to point me into.
#1- I built a 331 Stroker with Sniper EFI, and a 4r70w trans. My Lunati cam is only pulling 12 at idle, and the brakes are lackluster. At speed (say 40mph) when you come off the gas and the engine goes to full vacuum, it only takes a tiny touch and the brakes are activated. At a stoplight or pulling out of a parking spot with no throttle, they are no where near as reactive. Should I try a booster or should I just swap to a manual wilwood brake?
#2- I've had nothing but a horrible time with the rear drums. Once I got it on the road, the rear drums didn't work at all. I couldn't jack up the rear and put it in gear and have the rear tire stop. They would just spin through the braking. The previous owner just slapped something on when I bought the rolling chassis, and I found the brakes to be a disaster. I pulled them completely off to the wheel cylinders and replaced with new cylinders, drums, pads and hardware. The drums/pads/hardware came as a kit from RockAuto on the Powerstop brand. Now, I've adjusted them multiple times. I've rechecked everything with the installation. But when I apply any type of moderate brake, the rear drums shudder so hard and shake the heck outta the back of the car.
Any thoughts on #1, and any direction on #2 is appreciated. I'm at my wits end with the drum brakes before I pull them off and just buy a rear disc conversion.
Thanks guys!
