A DIY Pressure Brake Bleeder

A DIY Pressure Brake Bleeder
A pressure brake bleeder is a handy device to change the brake fluid in your car or motorbike.

The pressurizing of the brake system turns this fiddly chore into a one man operation, removing the need to have someone in the drivers seat pumping the brake pedal, with all the shouting that accompanies it.


Caution:
When working with brake fluid observe the cautionary notices on the brake fluid bottle.

The working pressure for pressure bleeding brakes is approx 15 ~ 20 psi, 100 ~ 135 kPa.

 Exceeding the working pressures on the brake reservoir/master cylinder can destroy/rupture the brake system seals.

Basically you need :
1. some sort of container to hold pressure and brake fluid.
2. tubing and connectors ( Tyre tube connectors work well).
3. an adapter plate/cap for the brake master cylinder/clutch cylinder.

4 a gauge capable of 0 ~ 20 psi is an option too, I'll be using a compressor with its own built in gauges.

  I used a windscreen washer pressure bottle from an old VW beetle, this has a max pressure rating of 35psi, more than adequate for our purposes.


Motive Products  at  www.motiveproducts.com/  does the complete range of power brake bleeders for those looking for ideas.

It can be seen that a garden pressure sprayer, with the addition of a gauge would make a dandy makeshift brake bleeder.

Can I use this to bleed my brakes on a 1993 Toyota 4x4 pickup ? I'm replacing some corroded leaking brake lines as soon as the weather lightens up here in the Northeastern USA !
