I just replaced the front brake pads on our 2006 Scion. I did NOT remove the whole assembly as the roters did not need replacing or turning. I removed the center roter assembly, but not the frame around it. I did NOT take off the hydrolic lines or open the bleed nut. It is the easiest and most straight-forward pad replacement I've ever done. Unfortunately, when I finished and went to test drive it, the Scion wouldn't move. It acts like the wheels are locked from turning. I can start it, turn the wheels, put it in gear, pull the emergency brake on and release it, but the rig just won't budge. Any ideas? Thanks, Bill

Remove the wheel, Remove the brake calipers, simply grab and pull the rotor off. Install new rotor, then push the piston back into the caliper a little ways, or all the way if installing new pads. This can be done using the old brake pad and a c-clamp to push the piston down. Install new pads and install the caliper. Install the wheel and torque to atleast 80 foot pounds. I torque mine to 100. Torque is important so as not to warp the new rotor.

you need to remove wheel, you will need to remove the caliper and caliper holder, 3 bolts on bottom of the ball joint, 2 bolts holding shock tube, need to unbend the indent on the axle nut, then you need a socket that will fit the nut, remove the nut, there will be a ball joint, with a cotter pin in it, take it out and loosen nut don't take it off all the way, with nut on hit with a hammer, it will loosen up then take off the nut, this will allow the whole assembly to come off axle, then you take the assembly to a shop that will press out the old bearing and put the new one in, I suggest doing both, even if only one is making a grinding noise, after all is done and new ones are in reverse the way you took off

Rear disk need turning, did you turn new roters when you replace them on the front I always did and found most new roters are not true. If it isn't a roter problem check front end parts for looseness such as idler arm

ok have ever had the breakes changed before or is there any squeling or grinding thats your brake pads are bad. as far as the whole brake system being replace thats ********* that mechanic is looking for a big bonus. im leaning towards a stuck or sticking calipar would cause it as well as if there is are in the system and will need to be bleed out. no if the roter's are warped u will know it cause the whole front end will shake when step on the brakes but only when u use the brakes. if you can see the brake roter's run your finger tip accros them they should be smooth with no groves or rigges if they have them the pads are bad as well as the roters and will need to be replaced, and a abs secner would kick in the abs. all in all i would take it to a shop u trust.

   this section.
   
2. Remove or disconnect the following:
   
   
   
   • Front wheel
     
   • Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads
     and the 4 anti-squeal shims

To Install:

CAUTION
Only replace brake pads on 1 side of the
vehicle at a time. Failure to use this procedure could cause the caliper pistons
on the opposite side of the vehicle to pop out requiring the reconditioning or
replacement of the brake caliper.

1. Remove a small amount of brake fluid from the master cylinder.
   
2. Install a used brake pad into the caliper and compress the caliper pistons.
   
3. Apply disc brake grease to both sides of the inner anti-squeal shims.
   
4. Install or connect the following:
   
   
   
   • Anti-squeal shims to the new brake pads
     NOTE: When replacing worn pads, the anti-squeal shims must be replaced
     together with the pads.
     
     
   • 2 brake pads
     
   • Anti-rattle spring and the 2 caliper pins
     
   • Clip
     
   • Front wheel
   
   
5. Depress the brake pedal several times to seat the brake pads.
   
6. Check the brake fluid level and top off as needed.

   • 2 cylinder slide pins from rear caliper assembly
     
   • Caliper assembly from rear caliper mounting
     
   • 2 brake pads with anti-squeal shims from rear caliper mounting
     
   • 2 anti-squeal shims from each disc brake pads
     
   • Pad wear indicator plate from the inner side disc brake pad
     
   • 4 pad support plates from the rear caliper mounting

To Install:

1. Install or connect the following:
   
   
   
   • 4 pad support plates on the rear caliper mounting
     
   • Pad wear indicator plate on the inside brake pad
     Note: Install the pad wear indicator facing downward.
     
     
   • Anti-squeal shims on each brake pad
     
   • 2 disc brake pads with anti-squeal shims to the caliper assembly
   
   
2. Apply lithium soap base glycol grease to the sliding part of 2 caliper slide
   pins.
   
3. Install or connect the following:
   
   
   
   • Disc brake caliper assembly with 2 caliper slide pins

     1. Torque to 90 ft-lbs (123 Nm)
     
     
   • Front wheel

ABS only senses if the wheel is spinning or not.
"Thumping sound" sounds like a bad problem. I've not had thumping sound from my front brakes ever.
I don't know how a caliper could cause thumping.
Is everything installed correctly and do the brakes stop the car??

Did you try disconnecting the battery for a few ...Its worth a try...???

front is as same as gm, 2 on caliper do not forget to press caliper pistons back into themselves, then just take pads out and replace then, install and start car and press on brake to bring pressure back into caliper

This video will show you how.

I turn them on a brake lathe in my shop whenever I change brake pads for customers. Heavy repeated braking will make em warp and vibrate like that. also changing the pads without turning them on a lathe will often leave them warped. Usually caused by either overheating during heavy braking effort or very commonly, using too heavy an impact wrench to tighten the lug nuts up. Did u get your tires changed recently? if so, dont go there again. their impact wrench is not set right and is likely overtightening the lug nuts.
Get a local garage/NAPA to turn the rotors and replace the pads. If the vibration is very severe you will have to replace the rotors.
Hope this helps if so pls rate my answer!
