Earls Solo Bleeders

[GregP27]

Hi,

Does anyone know the brake bleed screw sizes for the 2019 PP1 package? I have one coming and want to add Earls Solo Bleeders.

In case you haven't heard of them, they have an angled surface and you screw them into the bleed holes. When you want to bleed, you back them off about 2 turns and a spring keeps the line sealed when you release the brake pedal and allows fluid / air leakage under pressure. Makes bleeding brakes SIMPLE!

But. you need the bleeder screw thread size to order. Hence, my questions above?

You might want to check these out for yourself, assuming you want to bleed or, more likely, change fluid types.

In my 2002 Camaro SS, I went through the infield on Portland International Raceway because I had not changed from the stock DOT 3 fluid yet. When I did, I had no damage other than ego, and cruised back to the pits, changed to DOT 5 and had no more fade.

The 2019 Mustang GT PP1 I have oorder comes with DOT 4 I believe, but I still want solo bleeders on it if possible.

Thanks in advance for you answer, and try a pair for yourself. Sure helped ME back in the day.

I couldn't find bleeder screws for our cars when I went looking last time. I have a spare bleed screw somewhere but I don't know the thread specs.

The local racer supply store had a fluid catch bottle with a check valve built in, for like $10. It does the same thing a solo bleeder does, but works on any car or screw if the line fits. Much cheaper and simpler to locate the check valve in a bottle than inside the screw, and less likely to break on you.

Now I use a Motive pressure bleeder (which I think is what most of us who track regularly use). The pressure bleeder is even less likely to let air back into the system, and automatically takes care of keeping the reservoir topped off as you go. The other advantage to a pressure bleeder, is you don't have to be in the car working the brake pedal, you can sit at the caliper and observe for bubbles or discolored fluid, which is a big deal. No more wondering if you had air in the system or not. Its a better way to bleed IMHO and costs less than a set of speed bleeders. Remember, we have 6 bleed screws on a PP car. Two per front caliper, and 1 per rear. The pressure bleeder can be used for other cars too, all you need is the adapter for the reservoir cap, so its a better long-term buy.

I've also used (and do own) the Motive Bleeder. It works well, but these solo bleeder screws intrigue me. I've found that, with my car, the power bleeder is good for like a 95% good bleed, but a good old fashioned foot bleed after does a better job. This would allow for that. On my friend's S550, the power bleeder worked perfectly.

I'll take the bleed screw off the Brembos I have on my shelf and try to match a nut at Ace hardware.

Hi guys, I appreciate the answers. I'll look into a Motive Bleeder, but I had really good results using the Earls solo bleeders at a track after I boiled the stock DOT 3 in my new 2002 Camaro SS (Portland Int'l Raceway), back in 2002. I sold that Camaro about 4 years back and have ordered a 2019 Mustang GT Premium PP1, 6-speed. Due in 13 March. I'm hoping these cars come with DOT 4 and I may not need a fluid change, but I went from DOT 3 to DOT 5 at the track back in 2002, after having the brake pedal go to the floor at 145 mph with no slowing at the chicane after 3 laps. Since there was nothing in front but grass, I just went right through said grass, downshifted slowly, go back on track, and went to the pits to change fluids.

Not sure I want to repeat that one since it is about the only place I can think of where doing that with no damage is even possible ... and I'm not in Portland anymore.

Worst comes to worse, I'll check when my car come in. But .. thus Motive Bleeder sounds very nice. Again, I think you.

Cheers!

I got really serious about trying to find speed bleeders when I picked up my car a year ago. I couldnt find any info on it after a fairly exhaustive search. I've just been using a buddy (or and angry unwilling wife) and the peddle method. Ill be picking up a motive bleeder for this track season though.

The Mustangs come with Ford Motorcraft Dot4 Low Viscosity fluid, and assuming the fluid isn't too old, its usually sufficient for novice drivers at HPDE events. If you upgrade tires, and start pushing the car hard, then you can upgrade to an even higher boiling point track DOT4 fluid, like Motul 660 or Castrol SRF.

Over time Dot4 fluids will absorb moisture which lowers the boiling point, so if yours is more than a year or so old, or is discolored, consider flushing it before a track day.

I got @jbird60 trying to find the bleed screw specs

Thank you NightmareMoon and BmacIL. I appreciate your help.

I see MightmareMoon is in Austin. I lived there in 2005 - 2006. I was near the Solectron plant, also near Dell. Where do you go for track day?

And again, thank you, BmacIL. Seems like Earls would have a model-specific product selector, but they are in the UK and probably don't think they need that. It's easy to find thread specs for British cars, but all we get for U.S. cars is a sales brochure and some basic numbers.

Ah well, all's well thaht ends well, as they say. Cheers!

NightmareMoon, I see you live in Austin. I was there for a year back in 2005 - 2006 >here do you go for track day?

And again, thanks, BmacIL. You'd think Earls could have a model-specific lookup but, being based in the UK, maybe they don't need it. You can easily find threads for British cars but all we get in the U.S.A. is hopped-up sales brochures with a few numbers in the so-called "specs."

Cheers!

We have a few tracks w/in a day’s drive. Circuit of the Americas, Harris Hill Road, and Driveway Auatin are w/in 30 minutes.

MSR Houston and MSR Cresson are w/in a Day, also Eagles Canyon

Brembos are M10x1.0. 4 pot GT brakes are M8x1.0. The rears TBD. If I had to guess, M8x1 or M7x1. Still waiting on lengths, too.

Wow BmacIL, thank you very much!
