This is a frequent SAFETY issue that comes to me.
********************************

One of the most COMMON mistakes when replacing the rear brake caliper is....

Putting them on the WRONG side, this places the caliper bleed screw on the BOTTOM, the most intensive bleeding will at best give a spongy (low) brake pedal...


The caliper BLEED screw MUST be at the TOP !!!

This is not neurosurgery or rocket science!!!

If your eyes work, and you have ever watched BUBBLES rise in a glass of soda...

The caliper BLEED screw MUST be at the TOP !!!

Because of basic physics AIR rises in brake fluid.

The caliper BLEED screw MUST be at the TOP !!!

Discussion is FUTILE, the law of Physics already won...

When in doubt, consult the FOUR rules...

#1. The caliper BLEED screw MUST be at the TOP !!!

#2. The caliper BLEED screw MUST be at the TOP !!!

#3. The caliper BLEED screw MUST be at the TOP !!!

#4. The caliper BLEED screw MUST be at the TOP !!!
