Remote brake reservoir

Welder1 · Feb 8, 2015

I am think of fabricating a remote reservoir for M35A2 brake system and probably mounting it in the cab. I also would have it so I could pressurize it and use for a power bleeder. I am looking for input and any issues with this idea. I own a fab shop so building one is no issue just not sure how much pressure would be required I was think 10-15 psi. Let me know your thoughts.

You may be trying to reinvent the wheel here, a few vendors already make a kit to keep an eye on your fluid with a remote reservoir. When I install mine, I'll put in a 2 way valve to do just what you suggested...attach your power bleeder. You might not be real competitive in price if you'll be fabbing them in metal, these are injection molded plastic. Just my 2cents

I ordered a kit on ebay for my m35a2 58 bucks i think.

One thought on power bleeders in general. A few years (decades) ago in Auto Shop, we used a Snap On presure bleeder. It was nice. Held a gallon of fluid on the bottom of the tank. A diaphragm separated the air from the brake fluid. The reason, keep moisture out of the fluid. Air contains water, humidity. When air is compressed, the water is not. Even with a pharmaceutical air dryer, you still have moisture. Brake fluid absorbes water easily. Water and steel brake line is not good. Also the water will accumulate in the wheel cylinders. This is just my thoughts. I have done more brakes then I care to admit. I always have used the two person method.
The remote resovor is the best mod I have done. I put mine on fire wall so I can drop the side and check. It is easy and thus it is checked.

Military spec DOT 5 brake fluid won't absorb moisture .

Correct on Dot 5 ^

I made a small tank with PVC pipe and fittings. Strapped it in the cab corner and painted it OD green. I can stand on the running board, unscrew the cap, and check fluid level. the vent cap I made can have an air tank with about 10psi in it to pressure bleed the system. Cost me about 15 bucks to make and has worked well for about 4 yrs. BTW. Learned about it on this site so do a little search and get a lot of good info. Good brakes are a wonderful thing.

can I install a remote brake reservoir on my M35A2, it has air assist, or will it feed shared breather and ruin the air assist? top of master has single breather that goes to a 'T' on the frame where it picks a breather for the assist.

Rmtaunton · May 9, 2016

Yes you can just diconcect breather cap the t and put resovior on the breather cap

DeltaTodd · May 9, 2016

so the assist needs to be on its own breather or it will fill with brake fluid if it remains connected as it was originally and I attach a 'T' to the top of the master?

DeltaTodd · May 9, 2016

is the air assist destroyed if it has been hooked up this way and got brake fluid in it?

Rmtaunton · May 9, 2016

It wouldn't be good for it , but yes seperate the breather of the air pack and tie remote resovior to master cylinder cap

bonedoc · May 9, 2016

I ended up putting a shut off valve on my remote reservoir hose and added a T-fitting to the master cylinder cap with a removable plug. Allows me to shut off my reservoir, attach my bleeder, bleed brakes and put everything back with minimal hassle.

DeltaTodd · May 10, 2016

Thank you. I disconnected yesterdayand found that some brake fluid got into assist breather. could have been a real mess.....

Deuce brake reservoir trivia question..................
I finally found this thing, years ago I put it in a machinist box.

Does everybody know what this is and what it was designed to do?

jbayer · Sep 27, 2018

I don't about everybody, but yes I think I do.

Floridianson · Sep 27, 2018

Is the not go on the under side of the master cylinder cap. Prevents brake fluid from back splashing up the vent tube.

Okay, NOW everybody knows.
