Review of Eezibleed by George Murphy, Mercedes Benz Club of America Technical Committee

In past issues of The STAR, we’ve written of the importance of periodic brake fluid changes – at least once a year, preferably in the spring. For the do-it- yourselfer, this process usually requires two persons – one to pump the brake pedal and one to bleed the fluid from the brake cylinders. Recently, I found a device that makes changing brake fluid quick and simple.

Eezibleed is a pressure bleeding kit made by Gunson Ltd., in England. The kit eliminates all the hassles that have frustrated do-it-yourselfers in changing hydraulic brake and clutch system fluid. Eezibleed is deceptively simple to use but is functionally equivalent to pressure bleeders costing over a hundred dollars.

The patented Eezibleed kit consists of a special pressure bottle that holds one pint of new brake fluid; a clear plastic hose with a cap to fit the brake reservoir and an air hose that connects to a tire valve or regulated air supply. When both hoses are connected, all you do is open each bleeder screw, in turn, like a faucet, until clean fluid appears. The whole job can be done in less than 20 minutes.

The kit is available in the U.S. from John Abbott at Auto Expert Products Company, 2574 NW 29th Drive, Boca Raton, Florida 33434, 1-800-795-6958. John will “customize” your kit to include a cap to fit the Mercedes-Benz brake fluid reservoir and he pressure tests each unit to ensure that all seals and fittings are tight. The special 44mm cap fits most other European cars such as Porsche, BMW, Audi, VW, Saab, and Fiat.


1. Remove the brake fluid reservoir cap, install the special Mercedes-Benz size cap and connect it to the Eezibleed bottle as shown in the photograph.

2. For a source if air pressure, you may use your spare tire, an air tank or other air pressure source. Just make sure that the pressure is about 20 psi before starting the job. Too much pressure could cause a connection to blow off and spill brake fluid on surrounding surfaces. After the Eezibleed bottle is connected, check the system for air leaks. To reduce mixing old and new fluid, partially drain the brake fluid reservoir by opening a bleed nipple at a front tire and then one at a rear tire to drain some fluid from both portions of the reservoir into a bottle.

3. Fill the Eezibleed bottle with new brake fluid (Mercedes-Benz or Castrol LMA DOT 4). Then connect the bottle to the brake fluid reservoir so it will remain vertical and not be disturbed during bleeding,

4. Pressurize Eezibleed by connecting the air line to a pressure source, preferably your spare tire – bleed it down to about 20 psi. (This pressure should not be exceeded for efficient bleeding).

5. Connect a bleed tube to the brake bleed nipple on the right rear wheel and place the end of the tube in a clear container. (I recommend a clear plastic bottle – emptying glass Smirnoff or Jack Daniels bottles for use on this job can lead to unclear thinking and produce uncertain results).

6. With a correct size wrench, open the bleed valve until the fluid entering the container is clean and air-free. Then retighten the bleed valve.

7 . Repeat the operation on the left rear wheel. The Eezibleed bottle should hold enough fluid to complete two wheels. When the fluid level in the Eezibleed bottle approaches the minimum level line, disconnect the pressure source and refill the Eezibleed bottle, then repeat steps 5 and 6 for the right front wheel and the left front wheel.

8. When all the lines have been bled, disconnect the air line from the spare tire before removing the Eezibleed bottle from the brake fluid reservoir.

9. Finally, replace the brake fluid reservoir cap after making sure the air hole is clear. (Be sure to re-inflate your spare tire to 35 psi).

I was able to bleed the brakes on a 1987 560SEL with ABS in about a half hour – we removed the rear wheels for better access to the rear brake bleed screws. The kit comes with a number of caps to fit different brake reservoirs. If you have an older Mercedes-Benz, this kit will probably has a cap to fit.

For the do-it-yourself mechanic, this is a handy device and I recommend it for use on all cars. If you order a kit from John, be sure to specify the year and model of the car(s) you intend to work on.
