So i need ideas…… i changed out and replaced all brakes and rotors on the 240. The dust boot on my rear calipers are all twisted and looks like crap… one side looks like the rubber dust boot is about to fall out. Before i went 5 lug even before i had a brake booster i could ripp the ebrake and lock up my rears. Now i pull the ebrake and i don’t even feel it really tugging the car. I can slam the brake pedal and it doesn’t lock up the brakes at all. The rear brake calipers are twist in pistons and the fronts are press in pistons. My only thing that i can think off is maybe it needs to be bled again…… which idk why side there is no leaks that i can see and i didn’t open up the system to change brakes and rotors. Or maybe since the brake booster is from a 87 sentra the rod from the brake booster needs to be adjusted out so it pushs on the bmc more…( pedal travel may be different on the sentra than the 240sx)…. Weight between the two cars im ruleing out bc im completely gutted so im prolly the same weight as the sentra or close enough. But i still should be able to chuck the brakes …… im fine w.o having a e brake if it came down to it but im not fine with not be able to lock up the brakes if i need too. Any ideas.???

Btw my car is a s13 vh45 swap with a 87 sentra brake booster.
