Thread: B14 Brake upgrade question!

this is an SER disregard my name!!

So i have done the AD22 front brake upgrade. The Pedal is very spongy, and when im slowing down it shakes like the rotors are warped. I know thats not the case Cause I put another new set on and still shakes when im slowing down from 60MPH.

Now when I take the car up to 6k RPM the pedal stiffens and doesn't shake at all when slowing down.


I DON'T UNDERSTAND WHATS GOING ON!!

Please help!!!!

bleed the brakes properly ( sounds like air in the system for 1 part of the problem)

...next I'd check to make sure the sliders are in full working order (not sticking at all, free play, nothing missing or rotted out)

check all the connections between the IM and the break booster.

If there is no issues there rebleed the calipers.

The sequence is: rear right > left front > left rear > right front

If that dosnt fix the issue try rebleeding but starting at the master cyl.

So the Shop said there was no Air in the lines and i need a NEW MC...

I want to get the 1993-1995 Nissan Altima MC(U13)

Is this a direct fitment no mods needed?

Does any one have the Part number?

I dont have a part # but if your car is abs get abs,if not get non abs.I think its the 94ish SE that has the ABS one,but dont hold me to that. @speedricer may actually know the part# or more info since he got me one for my car

I dont have the part number. I just pulled it from the car. I can pull you one (think i have one sitting in my part bin actually now that i was gonna use for my upgrade). Next trip to the yard i can grab you one, dunno how earlier you need it though. I didnt recall any SE or anything, just look at the BMC and take note of how many lines are going into it. Dead giveaway lol
