Hey all,

After reading many folks comments about the evils of bleeding brakes with the old-fashioned two person depressing the brake pedal method, I have decided to change my bad ways. In the process of sourcing materials and hope that you all can help. As typical in this consumer age, there seems to be almost too many options making it difficult to separate the wheat from the chaff.

Below are some thoughts and questions that I hope someone can help me determine the best system at an economy target:
1) Is a one gallon sprayer the right size?
2) There are general sprayers, bleach sprayers, and deck stain sprayers; which ones have seals that are most compatible with brake fluid?
3) Since brake fluid is in the spray tank, are there some plastics in the pump and tank that are not compatible with brake fluid?
4) Is a pressure gauge really necessary?
5) Pressure relief valve systems seem to be a good idea for depressurizing, is it really necessary?
6) Where did you source good non-leaking quick connect fittings?


Thanks!

Paul

Search "Pressure brake bleeder" on Ebay. The first one on the list is $99.94 with free shipping, and it comes with an entire case filled with different adapters, a working quick-connect, a pressure gauge, and a bleeder that works without a lot of monkey motion and trial and error. Some things just aren't worth the hassle of trying to Rube Goldberg something together out of bits and pieces.

Paul;

Many years ago I followed HRL's advice and bought a manufactured brake bleeder. I recently needed to pump some gear oil and searched for a DIY solution. Here is pretty good documentation of a DIY build. DIY $20 Brake Bleeder

Another vote for Jerry's advice. I used one recently and it made the job super easy to do alone. Well worth the money to just buy one.

A bit off topic but I was using a vacuum bleeder tool. It’s a nice tool good for checking vacuum advance. But I found when trying to bleed brakes that it drew air in from around the bleed nipple rather the sucking air out the line.

Yup. They'll work, but you have to watch for that.

For a vacuum bleeder, I've found out it can help with a little sealer, or tape on the bleeder threads. It just needs to be able to draw a good flow of fluid through the system.

I bleed mine into another container with brake fluid. But same issues with air coming in through the nipple, I've coated grease around the bleeder and hadn't had any more air creeping in

I made one using a 16$ garden sprayer from Lowes. Works great, my dad borrowed it to do his 40 Chevy sedan also.
