TNTRower

I saw this same concept online for $60 plus shipping. It got me to thinking how to make it myself so my wife won't be bothered with pumping the brake pedal. Makes quick work of bleeding the brakes.

I have this in Word format with much higher resolution pictures. If you need or want that, just IM me with an e-mail to send it to.

Nice write up ......
Thanks for the tip this will be Super helpful... so you know if there is a special procedure to do this? I mean keeping the ABS in mind..... Does the car have to be on? I have only done this on other cars .....rather be safe with a benz... thanks

I left everything turned off. Went Passenger Rear Tire, Driver Rear Tire, Passenger Front Tire, Driver Front Tire for the order. I used synthetic DOT4 (Prestone). I wouldn't pressurize more than 20Psi. Bled until fluid came clean out of the bleeder valve.

Problem is, the factory specifies 2Bar.

What do you mean by "2BAR"?

TNTRower

1 Bar = 14.504 PSI

2 Bar therefore is 29.008 PSI. Therefore I stand by my previous statement of not more than 20 PSI

So if 2 bar (or 30psi) are required to bleed the brakes on a Benz, how is this device going to be of use

TNTRower

Huh?

You can accurately pressurize the pump up to 60 Psi. I said that I would not go much more than 20. It is a little bit of elbow work but still very easy to pressurize the system.

I guess I was not being clear enough, my apologies for that. This tool worked well for me. If you have the Motive brand of a similar design, you know it works as well.

So in order for it to be of use it has to work. Mine does. Therefore it is useful. In addition it allows me to bleed the brakes as a one man job. Very useful.

I guess I am not understanding where your question comes from.

The brakes need to be bled at 30PSI. You say you don't want to exceed 20 PSI. I see a conflict.

TNTRower

No conflict really. I just pressurized under 20PSI. It pushed all the fluid out very well. When a manufacturer says not to exceed a certain pressure it is generally over pressure that is the problem. If there was not enough pressure then you would not be able to get fluid through the bleed valves. You create too much pressure then you risk damaging the ABS system (sensors).
