MG MGA - Speed Bleeders

Anyone have a source for Speed Bleeder valves for MGA 1500? (4 drums) Time to replace hoses anyway so may as well do it now. Thanks!
Steve Simmons

Hi Steve,
I don't know of a source for speed bleeders, but I have used the EZ-Bleed sold by Jeff Zorn at Little Britsh Car Co. and Moss among others, and once it is set up I have been able to bleed and flush all the brakes and clutch in a few minutes. It take longer to move the waste jar and tube than to bleed the next cylinder.

I bought mine (4) "Speed Bleeder" #12701 from "Advance Auto Parts" I'm sure "NAPA", "Car Quest" or "Autozone" would care them also... they're a great help especially if you're using silicone brake fluid.. Mike

Mike, is that the proper part number for MGA drums?

These things look like the ducks....

I'll email Moss UK and see if they supply... and get there part number.

From there Sizes page does anyone know what the size's (SAE) for MGA's should be....
I'm interested in the Dunlop Twin Cam one's though, which look identical to MGB front one's.

Steve, luckly I saved the packaged that the bleeders came in. It reads "HELP" Speed Bleeder #12701: thd size 3/8"-24: overall lg 1.19". My MGA is a 1958 roadster. I did replaces all the wheel cylinders with a kit from Victoria British Ltd. and these bleeders did fit.. The old bleeders fit also.... They're two to a box not sure of the price?? Mike

I had never seen those before, they are pretty slick. One dumb question though, on a bleed after hydraulic work, not just pumping new fluid through as a flush, how can you tell if all the air is out if you are inside the car pumping the pedal? Do you just assume that 4 pumps or whatever amount is enough? I think you would still need 2 people to do it right, but at least you wouldn't have to keep opening and closing the bleeders, so it would definitely be a lot faster.

Ralph,
You would install a piece of tubing on the bleeder and route it into a bottle or cup. When you finish the bleedint, you should have fluid in the cup or bottle. If you don't, you haven't bled it enough.

Hi Mike,
Yea, that's how I do it. Whether doing it the old 2 person way, or with an EZ bleed, I start out with some brake fluid in the jar, and the end of the tube inserted into the brake fluid. Then I watch for bubbles coming out the end of the tube. Doing it with 2 people we keep repeating the bleeder open, pedal push down, bleeder close, pedal release routine until I have 3 pumps in a row with no more bubbles coming out of the end of the tube. This method has never failed, and I have never had to re=bleed a brake or clutch cylinder. I now have used the EZ Bleed and it is a snap, but still visually watching for bubbles. I just wonder without the visual of the air bubbles how you know if all the air is out. I suppose if you are by yourself and pump the pedal enough times you can assume that all the air is out, it seems like maybe a bit of guesswork
and may end up wasting a lot of brake fluid. I'm just wondering if it is feasable to do it by yourself. With the old 2 person method I have gone through my wife and all of my kids, and recently they seemed to all hide when I looked for a volunteer to push the pedal!! (LOL)
So I bought the EZ Bleed, and after using it I have seen the light.

I guess you can listen for the sound of the bubbles if the end of the pipe is submersed.

If you don't here anything then you should be finshed.

Plus always good to push through as much new fluid as possible, especially when using racing fluid.

What exactly is Ez Bleed.
Is it this ? or are they more screws ?

Hi Mark,
Here is a link to Jeff Zorn's site Little British Car Company lbcarco.com
It pushes the fluid through the system with air pressure. You fill the reservoir jar with fluid and use air pressure from a tire. It's simple but works really well. I used a spare trailer tire. You set the air in the tire to an approximate pressure specified in the instructions I believe it was 10-15 psi. You put the special cap provided in the kit on to the top of the master cylinder, and connect the air ine to the to the tire valve. Then you go to your bleeders and use the plastic tube provided and a glass jar. You crack the bleeder open and the air and/or fluid goes into the jar. Air will come out in about 2-3 seconds and if you want to flush you just leave the bleeder open longer. You then move on to the next bleeder and check the brake fluid level in the reservoir jar after a while. If you start out with a waste jar that holds less fluid than the reservoir jar you don't have to worry about refilling the reservoir until the waste jar is full.

When I did the bleeding by myself, I used to run a LONG HOSE to the jar where I could both hear and SEE the not-so-pretty bubbles! I ran a piece of wire coathanger through the hose into the jar so that the extra weight would keep the hose from jumping out of the jar during the operation! Those one-way valve hoses work great,also. You can also fit a Vacuum Pump to "suck" out the brake fluid & bubbles at the bleeder fitting WITHOUT HITTING THE BRAKES AT ALL! Just pump until you see no more bubbles. DON'T PUSH DOWN THE BRAKE PEDAL WITH THE (USUALLY PLASTIC) VACUUM PUMP ATTACHED AT THE BLEEDER FITTING OR YOU WILL CRACK THE PUMP HOUSING! You have up to 2,000 PSI at the DISK BRAKES!
