my brake pedal recently feels weird, when im in drive or reverse ,not when braking in neutral, the pedal feels like its pumping air rappidly, and u could hear it to, sounds like air pumping , i recently changed my brakes and did a flush , i took out all the air!!!!! and refilled it with dot 4 fluid need help!!!!!!!!!! plz,,,ps my brakes stop great, and dont really have to push them down for them 2 stop

 

i think the correct term for this is,' Brake Pedal Pulsates)

 

bump, is anyone goin 2 help me?or i just take it mits and get something dumb like you need an entirely new braking system,lol

 

u prolly should of used dot 3, dot 4 can corrode the **** in your braking system if its not made for it

 

but the brake tank says dot 3 or 4, so i hould just flush it and get dot 3 or wat?

 

Natural question - are you SURE you got all the air out of the lines?

 

yes, my mom pumped the brakes and i closed them,lol,im gona check my lines later, and i f i need to , ill reflush them

 

Time for SpeedBleeders. Let mom get back in the kitchen...

Might be a good idea just to recheck them. Things can go wrong from time to time. Also, maybe an air buble got sucked in the master cylinder when you were doing it. You never know.

 

just checked them now, i found out its becuz my engine shakes when the ac is on, and with ac off the brake pedal doesn't do that, im thinking i need to get new spark plugs

 

Um, no.
You need to not use the A/C. Your engine shakes because the weak little motor has to work harder, and the mushy stock motor mounts allow it to move around.

Now you know.

 

yep, i need the ac though i live in central texas, its hot and humid, today was high 93 AND low 82
