Russell 639630 Domestic Speed Bleeder 10Mm X 1.00

They do have a larger bolt head, 12 mm instead of 10mm for the OEM brake bleeder. For the front calipers you'll need a regular open 12mm wrench to turn them as a 12 socket hits the caliper hardline next to the bleeder, as does a 12 mm flare nut wrench. Not a big deal, as long as the OEM units arent seized in place in front, as as socket is best option to get the old ones out.Use Liquid Wench penetrant before you try and take the old units out.

They work as advertised, my only complaint is the higher price.

According to their website, the same part works in the front and rear calipers. I found out the hard way they do not. Rears were perfect. Removed OEM screw, installed Russell screw, bled brakes. Got to the fronts and did the passenger side and thought I was doing fine when I saw clear fluid coming out of the tube. Tightened it up, put the wheel back on and proceeded to work on the driver side. Clear fluid came out the driver side and I was happy. Tightened it up, put the wheel back on and lowered the truck. Noticed a puddle of brake fluid under the front passenger side. Crawl down there and thought maybe I forgot to tighten it. So I turned it just a hair more thinking maybe the thread sealant prevented it from fully seating. Jump in the truck to pump the brakes to confirm, and they sink to the floor. Get out of the truck and see a puddle of fluid under both front tires. So yeah, front bleeder screws are 1.4" and the rears are 1.25" Correct Russell part numbers are: Front 639560 (size M10 x 1.0 x 1.4) Rear 639630 (size M10 x 1.0 x 1.25)They don't have a customer service e-mail and I was waiting on hold too on the phone. The pictures show the difference in length for the front and rear bleeder screws.

These things are absolutely fantastic to use. Just replace bleeder valves with these, tighten them down, back it off a quarter turn, attach a plastic tube to get the brake fluid away to a catch container and go. I was able to bleed all 4 brakes in a matter of minutes (took longer to take off the tires). I would fill the brake reservoir max and press the pedal 12 times (takes it to the reservoir minimum level) on each wheel. I pretty much flushed out the brake system. The brake pedal pressure feels great. Can't be happier. I would absolutely recommend these to anybody.

This is my second set of Speed Bleeders. And safe to say that there's really no better upgrade than these. Makes bleeding your brakes 10x easier.

Had crusty and seized bleeder valves in the stock calipers on my C5 Corvette, so I decided to replace them. These fit perfect and bled super well. My brake pedal is nice and stiff after bleeding them properly with these valves. Great product for a great price. These come in PAIRS, so buy 2 sets if doing all 4 corners.

I bought 8 total, two for each caliper. Most worked as designed, except one of them didn't and acted like a regular bleeder valve, sucking back in when I lift off the pedal. I'm going to replace it with one from speed bleeder dot com. Haven't had one of those not work yet, I just needed faster delivery so went with these on amazon.

Love having speed bleeders. These fit an 04 mustang cobra rear caliper. Crack it open, have a hose to aim to the ground, fire away a few times. That easy.

Works as described.

Does not work

Bleed screws with a check valve make bleeding breaks much easier
