Front pad replacement the correct method for replaceing front disc pads

probably find that the calliper body is not moving freely on the mounting pins and leaving one pad in contact with the disc
quality of the disc is important
when working on disc brakes , replace both rotors and use the same pads for both sides
check the wheel bearings for correct adjustment

remove the callipers from off the disc rotors. remove the loose pad and use a piston mover to push the inner pad and piston fully back into the calliper .replace the pads and slip calliper back over the disc and re-tension mount bolts
make all spring and plates are replaced in the correct positions
when doing this I open the bleed nipple for the calliper I am working on as I push the piston back. It makes it easier and doesn't overfill the reservoir. When the piston is full back tighten the bleed screw
when the job is done pump the brake pedal several times to adjust the clearance of the pads back onto the disc.

first check the pads have not worn down to metal if they have the disc will have to be replaced , if the disc is in good condition and the pistons are free press them back into the cylinders and then the pads can removed .check the master cylinder does not over flow as the pistons are pushed back. Brake fluid is a paint remover. the wheel bearings don't have to be touched to replace pads. After new pads are fitted the brakes will have pumped to bring the pads out to the disc.

remove caliper, push disc all way home, put wheel nut on to hold home, retry fitting them the disc may be slightly scued. If no go try diffrent brand of pad I had same prob with a diffrent car last week & diffrent brand pad was 2mm thiner. If can't exchange pads get piece of emery paper on flat surface & sand away top part of pad material in round motions both ways till they fit. :-)

Removal & Installation
Front





3.4L front disc brake assembly









4.0L and 4.7L front disc brake assembly




To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of
   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.

Rear
To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of
   this section.
   
2. Remove or disconnect the following:
   
   
   
   • Rear wheel
     
     
     
     
     
     
     
     
     
     
     
   • 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
     
   • Torque to 65 ft-lbs (88 Nm)
     
   • Rear wheel
   
   
4. Depress the brake pedal several times to seat the brake pads.
   
5. Check the brake fluid level and top off as needed.

Front
To Remove:

   this section.
   
2. Remove or disconnect the following:
   
   
   
   • Front wheel
     
   • Front brake caliper assembly
   
   
3. Make matchmarks on the disc and the axle hub.
   
4. Remove the front disc.

To Install:

1. Align matchmarks and disc onto axle hub.
   
2. Install or connect the following:
   
   
   
   • Front brake caliper assembly with the 2 bolts
     
     
     
     1. Torque to 90 ft-lbs (123 Nm)
     
     
   • Front wheel

That's to be expected and is completely normal.

Rear brake shoes as fitted to drum brakes can typically last up to 60k miles with periodic adjustments, but you have rear disc brakes and the shoes will typically last half of that.

Also, modern brake pads no longer contain asbestos and are now made using harder metallic compounds; the direct result is that brake discs (US=rotors) are also considered to be consumable items as they are worn down by the harder pads. It's not unusual to have to replace front discs every other pad change and rear ones with every pad change; in both cases the mileage will typically be around 30k miles on most models.

remove all connection bolts , clips. I then slowly pry the brakes as far from the rotor as posible ( depressing the brake cylinder) with tire tool or large screw driver, so the new thicker pads will go in with ease. Replace new pads acording to toyota and replace bolts/ clips. this method requires no bleeding of brakes.

replace the pads...there is a sensor on them that snaps in and when the pads get thin it will create a ground turning on the light...hope this helps

The hard part is pressing the caliper piston abck into the caliper so you can get the new, thicker pads over the rotor. A large C Clamp works best.

has long has you check that fluid and bleed the lines to avoid air pockets . make sure you apply that sqeek prevent on the back of the shoes r u will be bothered by the sqeek later.
