"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:

• Simply clean the area around the old bleeder screw so that no dirt or contaminants can get into the brake system.
• Remove the old bleeder screw and discard.
• Screw in the Speed Bleeder into the wheel cylinder or caliper until it seats.

• Unscrew the Speed Bleeder screw a 1/4 to 1/2 turn.

• Here comes the magical part. Slowly pump the brake pedal approximately 4-5 times. (You do not have to close the bleeder screw between pumps.) A one way check valve lets the air and fluid out when the pedal is pressed and closes between pumps preventing  new air from reentering the system between pumps.

• After bubble-free fluid comes out of the Speed Bleeder screw, close the Speed Bleeder screw until it seats.

• Proceed to the next wheel cylinder or caliper until all are bled.

That's all there is to bleeding brakes with the Speed Bleeder.

Installation Notes:

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.
