"I installed one in my '88 R100RT. I pumped out the old brake fluid, being careful not to empty the master cylinder, while adding DOT-5, until it came out clear and fresh. Now that I have DOT-5 installed, it will be my last brake fluid change, but it was worth it for even one change. The guys who like DOT-4, and who have to change fluid every year, will just love Speed Bleeders."
"Performed exactly as advertised. Saved me a lot of work playing around turning the valve on and off. My compliments for a well-designed product. Will recommend it to my friends."
Installation of Speed Bleeder
Once you get your Speed Bleeder screw, it is very simple to install:
That's all there is to bleeding brakes with the Speed Bleeder.
Speed Bleeders are made from one of these four hex stock sizes...
1/4" hex, 5/16" hex, 3/8" hex, 7/16" hex
This also applies to metric sizes. This means that metric wrenches will not work with Speed Bleeder even though it might have a metric sized thread. You have to use an inch wrench or SAE wrench size. The reason is that metric hex stock is not readily available at a reasonable price in this country.
When you first install the Speed Bleeder you will note a slight resistance when you reach the thread sealant. This is normal. The thread sealant is conforming to the shape of the threads to provide a seal between the internal threads of the caliper or wheel cylinder and the external threads of the Speed Bleeder. When the Speed Bleeder bottoms out, it is closed. If it still leaks tighten it a little more. (no more than 1/8 turn) If you tighten it more you might break it off.
If you experience considerable resistance, more than usual, when installing the Speed Bleeder you might have cross threaded the Speed Bleeder. If you have done this you probably have damaged the threads on the Speed Bleeder and should not use the damaged Speed Bleeder.
***DO NOT OVER TIGHTEN***
On an aluminum caliper you could strip out the internal threads of the caliper and on a cast iron caliper or wheel cylinder you could strip off the threads on the Speed Bleeder screw.
Speed Bleeder screws are intentionally not case hardened. This makes it easy to remove if you break one off in the wheel cylinder or caliper. A case hardened bleeder screw is very hard if next to impossible to remove.
Slipping a piece of our silicone tubing onto the nipple of the Speed Bleeder screw and placing the other end onto our Speed Bleeder Bag makes it easy to see when the bubble-free brake fluid appears and lets you know it is time to close the Speed Bleeder screw . It also eliminates the usual mess associated with bleeding brakes.
