How to Install Front Brake Pads
1990-1994 Lexus LS400
This tutorial is for front brake pads only. If you're replacing rotors as well follow the rotor & pad tutorial. It's a good idea to replace your rotors and pads at the same time. If your rotors are not warped then you can probably get by replacing the pads only.

1) Loosen the lug nuts and then jack up the front of the car and put it on jack stands. Remove wheels.

2) Remove this top 14mm bolt. No need to take off the others.

3) Swing the piston assembly down. You may want to support it with something since it's heavy.

4) Remove the two pins and pull out the old pads.

5) Take off the old metal shim pieces and install them on the new pads. You may want to apply some brake quiet on the shims before installing them.

7) Open up the hood and remove the cap on the brake fluid reservoir. Put a shop towel or rag around the brake fluid reservoir just in case. BE CAREFUL: BRAKE FLUID DESTROYS PAINT.

8) Push in the brake pistons all the way. I used a short 1" dowel against the piston and the Lexus tire iron for leverage to push the piston in. You can also use a brake piston compression tool. With the piston retracted swing the piston assembly up into place. Torque the 14mm bolt to 25 ft-lb (34 Nm, 350 kg-cm).
9) Replace pads on the other side.
10) Check the brake fluid reservoir to make sure it's at the appropriate level and add/remove fluid if needed.
