Brake Bleeding Tips
Bleeding the brakes on a GL1000 is straightforward and well-covered in any manual. However, this can be a most aggravating task. Below are some tips to reduce your frustration.
February is Customization Month!
For many of us, our motorcycle is an extension of our personality. A two-wheeled conglomerate of metal and self-expression. This month’s featured products are dedicated to those individuals eager to chop, weld, bend, and customize their bike into a 1-of-1 kind of ride.

“Reversed” Front Brake Calipers on Vintage Hondas?
On some bikes (including the Honda GL1000), the front calipers can actually be installed on the wrong side! Front brake calipers on all bikes must be installed with the bleed screw “up.”
This simple requirement can get corrupted when brake parts are carelessly “mixed-and matched” or installed without care. Whatever the explanation, this error leads to two serious issues:
- Brake hoses will be too short and “kinked” at an odd angle creating a serious safety hazard!
- Air bleed nipples with be rendered worthless, since they are no longer at the top of the caliper where air bubbles rise. The brake system can never be fully “bled” of trapped air.

Low Speed Wobble?
Diagram by Vittore Cossalter and Roberto Lot
I get this question frequently: “Do you know why if you let go of the handle bars under 30 mph my ‘Wing has a bad wobble?”
Early ‘Wings and most other bikes of this vintage don’t have any inherent wobble tendencies and they are rarely ridden at the “limit” where handling anomalies are magnified.
