So last night I was driving my 93 Accord and all of a sudden whenever I would step on the brakes I felt the pedal kinda jump up while I was stepping on the brakes. Is it possible that I might have air in the system?

 

Jump Up?

I'd bleed the system.

 

better word bounce up.
yea i was thinkin on doing that but i dont know how air would just get in there all of a sudden.. if thats wat it is.

 

Brake fluid tends to collect water over time. If you haven't flushed the system anytime recently it certainly is not going to hurt.

And by "bounce up" are you saying you push the pedal down and then it pops back towards you?

 

yea thats wat happens wen i push down on the pedal. i gonna definatly consider flushing the brake system.

 

As a side note, I had this occur to me on my DX Accord after it was sitting for awhile (maybe a week or so) I attributed it to the brakes leaving residue on the rotor or something similar. After driving around for a bit the issue went away.

 

it wouldnt hurt to flush it out, im leaning towards air in the system as well, if the problem isnt consistant.

 

sounds more like a warped rotor to me, try having it turned

 

Absolutely! It's time for the good ol pump n bleed sequence... she'll be better in no time.

 

so i just bled the brake system and still nothin.. im leanin torwards rotors been the problem but they r pretty new brembos..
so heres the story of how it all started 2 nights ago we were driving around driftin some corners and wen driving back home, i started heading and i started hearin a noise like the dust plate was rubing against the rim or somethin and also the brake pedal was spongy and the steerin wheel would shake get brake was pressed. so i got home and took the tire off and noticed that the 4 bolts on the hub were really loose so i tightened them and noise went away.. but the steerin wheel would still shake wen applied.. i changed the lower ball joints a while back possibly the hub wasnt pressed in right?
thanks for stickin with me on this one guys..
