Well my 2006 sonata had a bit of a shake when braking with the original brake pads about 60,000 miles old. So I had the front rotors resurfaced, and replaced the brake pads as you would with any other car. Now the car brake petal feels mushy and sometimes it feels like the the petal sinks to the floor. The brakes work fine except for the fact that the petal does not feel like it did before, it actually got worse in my opinion. Please let me know if there is a trick or if I am going crazy. Thanks : )
You have air in your break lines. The two ways you can solve this problem is have the breaks blead to get the air out of the lines, or you can take the top of the break reservoir and pump your breaks to the floor. DONOT DO THIS With the car moving. What this will do is force the air to the reservoir.

Try re-bleeding ALL wheels starting with furthest away - pass rear, then driv rear, then pass front and driv front. That should get your pedal back. To reset light you need ABS reset tool and it's EXPENSIVE. Have a good competent shop reset it for you. Body shops can reset them also.
will try to help. when front wheels shake while applying brakes and you can feel shake in steering wheel, front brakes and rotors need replacement.rotors are warped,if you replace front brake pads, it will return[shaking when you apply brakes] suggest that you replace front rotors[both] replace [both]front brake pads. cost? i would charge [brake pads cost $55.00] labor,$60.00] total $115.00 thank you for choosing fixya.com
it sounds like the master cylinder, but I would bleed the lines first, if that doesn't help then I would replace the cylinder. It is not that hard to replace just make sure you drain all the fluid first as it is very corrosive and bled the brakes once the new one it installed. it should not cost more the a couple hundred bucks. Good luck Tim
What it sounds like is you have very poor quality pads on the car. The subject of brake pads can go on for days. If it was me I would buy a top of the line name brand pads , if the rotors can be turned the turn them or replace them. Also struts and shocks that are old affect the brakes and stopping distance. I think someone has just sold you poor quality brakes. and if your rotors are warpped this will cause the wiggle you feel when stopping.
Most brake pads on GM products (and just about everyone else's) have little scrapers on the sides of the pads that will cause the brakes to squeak all the time when you wear down to their level. When you hear that constant noise it is time to replace the pads ASAP. If you put it off too long, you will probably end up replacing the rotors too. If you drive like me (jack rabbit starts and sudden stops) the original pads might make it to 35-50,000 miles. If you drive like a granny (slow starts and coasting to a stop) you might be looking at 45-60,000 miles before replacement.
