just bought a 93' del sol si and whenever i brake, the car shakes. any idea what the problem might be?

 

does the brake pedal pulsate as well?

 

my pedal pulsates, rotors' warped?

 

yep bad rotors will cause a pulsating brake pedal

 

Rotors are warped. Should change the pads too while you're at it.

 

From my experience, when the car shakes it's usually the rears that are warped. If steering wheel shakes then it's probably the fronts.

 

does it feel soft when braking?

 

shaking when braking could also be that the tires are unbalanced.

 

if the tires where unbalacnced it would shake at all times

 

u need a brake job. Unbalanced tires would shake at highspeed. Warped rotors shake while braking.

 

alighment would cause the shake at braking to but mostly rotors... probably the fronts....

 

most comonly its ur rotors. just be shure to get them replaced and also get new pads...

 

warped rotors, change them and you should be good.
i do recommend you get some good pads as well.

 

Also check the wheels. Aftermarket or OEM? Also wheel balance. If it's aftermarket, does the wheel have lug nut cover? Was the wheel balance WITH the cover on?

I know you mentioned while braking, but sometime that only shows when there is load, such as braking.

 

wheel balance/alignment will NOT cause a vibration while braking...im 99% sure it's your rotors

 

I'll agree with you. My reply was based on my own experience back in 97 with my brand new Civic. I went cheap and got a set of used aftermarket wheels. I had the tire shop check everything. And there were no solutions.

There was vibration when I go over 80mph and when braking. Never had problems with OEM.

Got a new set of wheels, and no vibration. So there must be something wrong with the wheels. One, all four, don't know. So just want to throw it out there since the car is old, the wheels might be "old" too.

 

time for new rotors, and pads too while you're at it.

 

dam, well anybody know where in around hayward area is a good place to get them checked? and also how much would it cost to get the rotors fixed + getting the pads changed?

 

def. warped rotors try doing it yourself and save the $$
