My car(DX EF) came with rear disc brakes and I don't know if they're off of an Si or an Integra. How would I be able to tell the difference? I was going to upgrade to just Brembo blanks all around and some brake pads, but I don't want to buy the pads or rotors for the wrong application. Also, how would I be able to tell the difference between the master cylinder, proportioning valve, and brake booster of a Civic or an Integra. I want to find out if the disc swap was done the right way.
Someone, help me out. Any info, suggestions, help, etc. will be appreciated. Thanks in advance.

the integra MC is bigger, im sorry if that doesnt help, try to find another ef with stock setup and compare.

for rotors you could remove both front and back from one side, and compare them by eye, if they look similar, he used civic EX ones, if not, probably integra.... you know?

 

Integra master cylinders are 15/16". Stock is 13/16". Proportioning valve should be 4040. Wouldn't pads and rotors be another one of those interchangeable items?

It's my understanding that all 88 to 2000 trailing arms are the same if you use the stock control arms. The exception is the DA. The only difference is the larger diameter trailing arm bushing.

Would I be able to swap a '94 and up LS prop. valve, master cylinder, and brake booster? Would it be a direct swap? I know the ones from a '90-'93 would work, but I don't know about the '94+

 

94 booster and master cylinder will bolt up, but you will have to bend one line and re-flare it to be larger. i think all 94 prop valves are for abs and different.

 

Are the pads interchangable?

 

Any civic or integra pads except the type r will fit the rear. 88-91 prelude will work as well. They all have the same rear brakes.
