Brake Service Update

Brake Service Update

For those of you who own my Goldwing Basics Maintenance DVDs or subscribe to my On Demand videos, you are probably aware of the MotionPro™ Mini Bleeders that I use in the video to bleed the brakes and clutch.

The Mini Bleeder is a great tool because it is three-tools-in-one. It is a socket, a wrench and a one-way check valve. When the bleed valve is opened (¼ turn), it allows air and old fluid to exit the valve when the brake or clutch lever/pedal is depressed, but will not allow air and fluid to return when the lever is released. This makes bleeding the system a one-man job. However, the Mini Bleeder is not without its problems. The attached socket wrench handle makes it difficult to attach to a bleed valve in a tight location. For example, on the right side of the Goldwing, you have to remove the brake caliper in order to attach the Mini Bleeder to the top bleed valve. Also, when bleeding the clutch, you have to remove the canister bracket to have enough space to attach the Mini Bleeder socket wrench.

Another option is the MotionPro Hydraulic Bleeder (shown below). This is a one-way check valve that sits between two pieces of clear tubing. This is a better solution as it does not require that you remove the right-side caliper to place the hose over the upper bleed valve, a big time saver.

However, this tool is also not without its problems. I found the tubing included with the tool to be slightly too large (inside diameter) to remain in place on the bleed valve tip. There is an included metal compression clip, but it is virtually impossible to access the clip in tight places to work it over the bleed valve nipple. One solution is to rig a smaller diameter flexible rubber hose in between the check valve and bleed valve. Why MotionPro does not include a smaller diameter hose in the first place is a mystery.

Here you can see the larger hose is almost read to slip off the bleed valve. A smaller I.D. flexible hose will correct this issue. MotionPro should include a smaller I.D. hose in the kit.

There is another solution that many Goldwing owners swear by; Speed Bleeder.

The Speed Bleeder is basically a replacement bleeder valve with a one-way check-valve built into it. Why all bleeder valves are not made this way to begin with is a mystery. To use the Speed Bleeder, you must first replace your existing bleeder valves with the Speed Bleeders. I have added a video on YouTube that shows how to install these (watch the video).

Once the Speed Bleeders are installed, you simply attach the rubber hose, which is supplied with the optional Speed Bleeder catch bag, open the Speed Bleeder ¼ turn, and pump away. Unlike the Motion Pro Hydraulic Bleeder, the hose that is supplied with the Speed Bleeder catch bag is the perfect size to fit snugly over the bleed valves.

After testing all three tools, I have come to the conclusion that the Speed Bleeders are the easiest way to bleed the brakes by yourself. It will cost about $50 to replace the eight bleeder valves on your Goldwing, but well worth the investment in my opinion.

You can order Speed Bleeders online from Shinhopples. You will need to order 8 Speed Bleeders. I also recommend that you order the Speed Bleeder Recovery Bag and Hose.
