Working at the shop I have to bleed brakes all the time. I have tried various special tools made for that. From speedbleers, to vaccum pumps, to cap pumps. Nothing seemed easy enough and fast.

So today my pal and I did something to make it very simple.

Drill a hole in the brake fluid reservoir cap. Install a rim valvestem in it. Thats all.

Then, after adjusting the compressor line pressure to about 15 psi, one person uses the tire inflator attachment and pressurizes the reservoir, the other one plays with the bleeder valves.

Takes about 1 min per bleeder. All the air gets out completely. So with huge brakes on all four corners on my car with 2 bleeders on each, we flushed the whole brake system in about 10 minutes.

No air at all.

Talk about a stiff brake pedal...

I doubt we are the first ones to do it, but it is fast easy and simple.

Just wanted to share that with you guys...

 

How do you keep it topped up while pushing air through it? You just stop when it's low and refill the reservoir?

Couldn't this allow water / debris into the braking system?

 

I keep topping it off...

Water and derbits, hehe, good point. I drain my compressor regularly and have a filter, so it is all good.

 

You could have also bought a pressure bleeder which does almost the same thing. You put the fluid in a separate container that is pressured. The pressurized fluid is then pumped into the system using a modified cap similar to yours. I use one to bleed the brakes on my car and the whole process takes less than ten minutes. I probably do it every 6 months or so. But, for the sake of simplicity, I do like your method.
