Setting the Piston 20º Angle, I get this question a lot... Options

[Eric_Shea]

I get this question a lot so I thought it might help to have it posted in a thread that can be searched etc.

The best way to set a piston angle without using the gauge is to draw an imaginary “Center Line” down the center of the pad cavity. This is illustrated by the “Red” line in this picture.

Set the angle facing the side that has the bleeder. This is illustrated by the yellow arrow in this picture. This denotes the “Top” of the caliper.

By setting the bottom notch of the piston on the center line it will automatically give you the 20º angle as illustrated by the “Green” line in this picture.

Thanks Jeff, that's probably a better picture to give people a more complete understanding.

It shows the center line and how it relates to the notch and the special tool used to position the pistons. I've used a green line here to illustrate once again.

The pads need to open into the face of the oncoming rotor.

I recently changed pads and rotors and simply pushed the pistons home with a c-clamp before inserting the new pads in the front, and used the adjusters to pull them home in the rear.

Did I miss some important step ??? And is this the front or rear you are referring to?

thx
