ok so i just installed my bbk and along with it are fresh new stop tech street performance pad. i have a few problems. 1) i have bled the brake system, no air bubbles, clean fluid flowing out so im 90% sure the system is bled. problem is, im still having spoongyish brake feel. it travels about 1/2 way between rest position and the floor. could it be that i havent bed in the pads yet cause this spongy feeling? i read somewhere that this exact pad can have that problem

second problem and this could possible answer the first. on my caliper, it has 2 bleeder valve. i bleed 3/4 calipers with both valve. however on the 4th caliper, passenger front, the outer valve is kinda stripped/striping. so i only used the inner valve. do i have to bleed BOTH valve? i notice as i was bleeding my 3rd valve, driver side front, that once the inner valve was bled, the outer didnt have any air in the fluids. so do i really need to bleed both valve?

any help/suggestions are appreciated

Yes you need to bleed both valves, air will easily get trapped and there is no way to bleed it out from the other bleed point.

Second, a pressure bleeder makes it a lot easier.

Third, without a pressure bleeder like I once did not have. I had to bleed the brakes every other day for a few days to get all the air out.

Last, it's the ABS unit that really likes to trap air, even with a pressure bleeder, it can tricky. Air gets trapped and takes forever to get out.

Definitely sounds like a motive power bleeder is a necessity for our brakes then. I know what is #2 on my tool list now lmao

I should have bought mine earlier. No I need adapters for my other cars.

I didnt let the system drain completely. Think theyre air in the abs? Also, where can i get the power bleeder? Ill try again i suppose.

Yes I do, I plug lines when I remove calipers and 3 out of 5 times air still gets there. Especially the fronts.

Best way to seal off the banjo bolt when removing your calipers is to use an acorn nut...they even have self-sealing acorn nuts:



Also keep the line as high as you can when disconnected.

Dont forget to use your rubber mallet to tap the calipers, lines, module... everything that may trap air, periodically rap to dislodge trapped bubbles during the bleeding process.
