My car has speed bleeders on each caliper. I just open each speed bleeder and use a $5 brake bleeder bottle to catch the fluid. I pump the pedal by hand while kneeling next to the car. The so-called easy methods usually end up making a mess.

I'm with RacerX, Motul RBF600. Have used multiple brands in the past and while it might be a little overkill in the SRF why risk it. It's not that expensive and saving a couple of bucks isn't worth maybe having problems with fluid at the track.

I think our pads (hawk blues) will quit before our fluid does. Anyone else seem to sense a little brake fade on really hot days on brake heavy tracks?

I've directed my brake cooling back to the calpers/disks as it was shortened and going nowhere and haven't felt it again but seems to indicate we're pushing the pads close to the limit without cooling?

I also use Motul RBF600. Amazon has it for a pretty good price.

If I can draft someone to man the pedal, the old fashioned way is easy and works great.

If I can't, then I've used this thing to pressure bleed:

Gunson G4062:

I hook it up to my air compressor and use about 15 psi.

You could probably build it yourself if you think it's easier than spending $50.

Thanks for help.


My car has speed bleeders, but I still like the Motive Power bleeder. It makes it easy to do a flush.

It is important to remove pressure by opening pressure bottle prior to removing cap from master cylinder or you will have a mess

Do you have a part number and vendor for the speed bleeders? The ones I ordered did not fit the calipers.
Thanks

When did they legalize speed bleeders?

I just got the power bleeder. Works easier than the broomstick to hold and bleed for single person setup. The downside is when I was flushing, I can't see the level to know when to stop. The girdling specific cap was extra; I could not find a vendor that had it as a single kit.
