Pressure Brake Bleeder

Post by WarrenD »

Has anyone successfully used a pressure bleeder on their M37? If so, which one?

Due to the location of the master cylinder I use an air operated suction bleeder. This attaches at the bleeder valve.

Yep, I use the Motive power bleeder and fabbed up a master cylinder cap for an adapter-works great! Sure beats the ol' "pump 'em up and hold the pedal" two-man dance. Here's an old thread search on it:

Thanks, I had heard from the car guys that the suction bleeders didn't work well. Seems like wheel cylinder replacement is a frequent thing (well, every 5 years or so, probably not driving it enough) and it's getting harder to get someone to pump the pedal while I dive under and play with the brake fluid.

I use a suction bleeder. It works great. Just don't wind the bleeder open or it will suck air at the threads. The slightest bit cracked open is sufficient. RR, LR, RF, LF.
