Are they even available? My new brakes should be arriving next week.

 

Although I've gotten the best results bleeding brakes the old fashioned way.

 

Open...close, open/close with someone else pumping. No thanks. I've been using speedbleeders for a few years and they make it a one man job. I'd like to think that pumping the pedal during the process evacuates fluid from more places (master/booster) than simply pushing new fluid through the lines with that vacuum contraption.

 

Soon to be added to the StopTech web site FAQ section:

What SpeedBleeder works in my StopTech caliper?

The thread pitch for bleed screws in all StopTech calipers (ST-20, ST-22, ST-40, ST-45 & ST-60) is M10 x 1.0. The correct SpeedBleeder part number is SB1010S. To look it up by application, the front caliper on a 1992-1997 Viper will get you the correct part. As a precaution, install any new bleed screw by hand to assure the proper thread pitch (don't use a wrench until the bleed screw bottoms out on its seat). Cross-threading the bleed screw port will damage the caliper beyond repair.
------------------------------------------

If using a pressure bleeder, be sure to use one of the very expensive ones that provides a diaphragm between the pressurized air and the fluid. Otherwise, you're pressurizing air directly in contact with the fluid, which will cause the air to be absorbed by the fluid. Even worse, pressurizing air causes moisture to condense out, which it does right into the brand new brake fluid you're pumping into your car. The result can be a spongy pedal that never goes away no matter how many times you bleed the brakes, and may also include EZ-boiling on the track.

I've been through this within the past six months with a tuner who should have known better. He put our ST-60s on his car and just couldn't get them working right. As soon as the system was flushed with non-corrupted fluid, everything became peachy.

What type of pressure bleeder do you recommend? The only one I've seen and used is the Motive.

 

Thanks for the info. I'll stick with speedbleeders for the time being then and pass on the expensive pressure bleeder.

FYI, I've been VERY impressed with everyone I've been in contact with at Stoptech over the last few months: yourself, Matt W, and Duane S. My questions have been THOROUGHLY answered promptly and above what I would have expected for an answer each time. Your team's dedication to customer service should be commended!

 

2nd stoptech support is great, which is why I went with them too.

 

Kudos to Stoptech for customer support. )

 

Google "pressure bleeder diaphragm"

 

Wouldn't you recommend the 1010S-SS (Stainless Steel?)
