So i just switched my stock 95 si suspension to wide 4 lug itr.

Ever since the swap, my pedals been sinking to the floor. Theres pressure, but then it loses pressure. After research and talking to people, we all came to conclusion that it was the master cylinder. Bought the 1 inch integra MC and brake booster and had it install. SAME PROBLEM!

So now, im thinking it's the calipers. Just wondering if there is any methods on how to check your calipers to see if they are bad.

Thanks!!

 

Mine is doing the exact same thing. did u bleed your breaks? Maybe contaminated fluid? I was thinking it was my MC or my brake booster but now since you posted this I dunno. I just don't see how it could be a caliper prolem. when a caliper drops it usually sticks and thats evident on the rake disc assmuming u have 4 wheel disc. I have a stock 93 Si and I dout it has anything to do with the swap. Did u happen to take off ur brake hose? I think maybe air is trapped or something. Im confused something is wrong.

 

Yes, i bleed the brake so many times i lost count. I even took it to the shop to do the machine bleeding to make sure there is no air at all trap in there.


The shop told me it has be to the caliper, because there is no leak threw the hose, and the MC and brake booster is good.

I just got the rear caliper from the stock si suspension, so i'll keep this post updated.

 

Any luck? I [freak]ed up the rubber seal on my rear caliper last break job so i think it might be the prob.

 

pull back on the rubber boot to see if there is any fluid leaking threw. If there is, it would be best to get new one.

 

So i figured out the problem. It was my calipars, the left side was on the right and the right was on the left, upsode down lol.

I guess the idiot i bought the suspension from must of not notice it and that might of been why he said me the suspenison for so cheap.

Anyways, shop told me if i ever have a pedal sinking probelm, do the following

-check for leaks on the calipars
-bleed whole brake system
-MC or Brake booster replacement depending on how the pedals feels
-look for incorrect bends on brake lines
-look to see if u have a defective crush washer ( washer that goes in between the brake line to the calipars)


Oh yeah, make sure your calipars isnt upside down either.
