4 wheel disc brakes, just replaced front calipers and rotors, new pads and wheel bearings. ABS light has been on for over a year, but just before replacing the front brakes the driver side brake locked up causing it to burn the pads !!!
The problem is when I start applying the brakes to stop or slow down from a speed of 35mph the brake pedal pulsates ,now if i'm attempting to slow down or stop from a speed of 45-60mph the brake pedal pulsates and the steering wheel starts shaking!!!! NEED A SOLUTION !!! PLEASE ANYONE KNOW HOW TO FIX THIS!!

    For whatever reason the front rotors are not running true!!! Have a 'MECHANIC' check the rotor runout!

    No that isn't the problem , I am a mechanic and I work for a machine shop! So yes I did check the runout but there is always a slight bit of runout because that little bit is what helps release the calipers from the rotor so the pads are not costanly dragging on the rotor, if that happen your brakes would burn up in 1000 miles and it would create so much heat the rotors would warp!!!
    SO THE ANSWER TO MY QUESTION THAT I ASKED,I ENDED UP FIGURE ITT OUT AFTER I REPLACED BOTH FRONT L&R CALIPERS, CALIPER MOUNTS, ROTORS FOR THE 2ND TIME AND A 2ND SET OF INNER AND OUTER WHEEL BEARINGS AND SEALS I THEN DROVE THE VAN FOR THE MANUFACTURERS DIRECTIONS ON BREAKING IN BOTH THE NEW PADS AND ROTORS WHICH DIDN'T CHANGE ANYTHINlllG SO AFTER DEBATING THE REST OF THE BRAKE SYSTEM I KEPT REMINDING MYSELF THAT I REPLACED THE REAR ROTORS AND PADS JUST BEFORE WINTER AND NEVER PUT IN ACCOUNT THAT MY VAN WASN'T DRIVEN ALL WINTER!!!
    LONG STORY SHORT AFTER WHAT STARTED MY ISSUE WAS A SIEZED FRONT CALIPER SO I REPLACED BOTH FRONT L&R ROTORS AND 1 CALIPER AND A SET OF PADS!! PROBLEM BECAME MORE PRONOUNCED!!! SO THINKING THE RUNOUT WAS TO EXTREME AND THE NEW CALIPER WAS GETTING REAL HOT SO THAT MADE ME THINK I HAD ASTICKY NEW CALIPER!!! AFTER TURNING IN THE NEW ROTORS AND THE 1 NEW CALIPER ON WARRENTY I THEN PICKED UP 2 NEW FRONT CALIPERS AND CALIPER MOUNTS AND HARDWARE ALSO NEW WHEEL BEARINGS AND SEALS FOR BOTH ROTORS , I THEN HAD THE RUNOUT CHECKED WHICH WAS PERFECT I ASSEMBLED THE FRONT BRAKES FOR THE 2ND TIME THEN RAN THE BRAKES THROUGH THE MANUFACTURERS RECOMMENDED BREAK IN PROCESS AND NO FREAKING CHANGE!!!!!! BEFORE I WENT CRAZY AND PULLED ALL MY HAIR OUT, I DECIDED TO REPLACE BOTH L&R REAR ROTORS ,BRAKE PADS, CALIPERS AND CALIPER MOUNTS !!!! AFTER COMPLETING THE INSTALL PROCESS INCLUDING BLEEDING BOTH L&R REAR BRAKE CALIPERS ??????????????? I THEN WENT AND TOOK MY VAN FOR ITS MAIDEN VOYAGE AND ........................ WELL AH NOO MORE PULSATING BRAKE PEDAL OR STEERING WHEEL THE BRAKES ARE AS GOOD IF NOT BETTER THAN WHEN THE VAN WAS BRAND NEW!!! LESSON LEARNED BEFORE REPLACING THE FRONT BRAKES FOR A 2ND TIME AROUND I WILL ALWAYS CHECK THE BACK BRAKES FOR ANY FLAW'S CREATED FROM SITTING FOR ANY AMOUNT OF TIME LONGER THAN A MONTH. !!!!!
    So for anyone who is having the same issue I have exspierenced and you already replaced the front brakes and before you decide to change the front brakes for a 2 time, make sure you check and rear brakes for ANY FLAWS and replace aLL THAT IS NEEDED AND SOMETIMES replace any òa
    parts that look OK but are not workkinn correctly
