The front and rear brakes are a separate system on most vehicles since aprox 1968. One bowl feeds the front and the other bowl feeds the rear. You have a fluid leak somewhere, have it checked out. The front (usually larger) bowl supplies the front brakes, the rear bowl supplies the rear brakes. Check the front brake system for leaks immediately, these are your primary power for stopping. It should also be noted that front brakes, typically disk brakes, due to wearing over time will cause the fluid level in the front reservoir to drop. This will occur over months or years and is normal and acceptable as long as the level remains above minimum and below maximum. Any time sudden fluid level drops are experienced, a leak is indicated and should be repaired immediately.

Why no brake pedal pressure when their are no leaks the system bled and anew master cylinder?

There is still air in the system. Some cars, GM for one have a master cylinder that sits at an angle. Some of these require you to jack up the back of the car to make it level. You bled the brakes starting at the back passenger wheel? You always bleed starting at the wheel farthest from the master cylinder. The easiest way to bleed brakes is this. Get a piece of tubing that will just fit over the bleeder screw. Loosen the screw, put the hose on it and the other end in a container with enough fluid in it to cover the end of the hose. Now slowly pump the brake pedal until most of the fluid is out of the reservoir. Refill the reservoir and tighten the bleeder screw. Move to the rear drivers side and do the same thing, then the front passenger and the front drivers last. Doing it this way you cannot get air back in the system. Sometimes bench bleeding the master is required before you install it.


Where is the brake fluid reservoir in a 84 VW Vanagon?

Remove the cover of the speedo and you will see there. Good luck. The cover over the speedometer and tachometer removes by pulling from the back to the front, and lifting up. You will find the brake fluid reservoir in the middle on top of the master cylinder. This also serves the clutch slave unit if you have a manual transmission. In addition, you will find two screw-in switches in the sides of the master cylinder, these are pressure activated and control the brake lights (a common failure item, and cheap to replace. Be sure to use Dot 3 or Dot 4 brake fluid, but NEVER Dot 5. Bleed the brakes at least once every two years. Don't forget to Bleed the clutch slave too. Be sure to place an old towel or rag around the reservoir when filling, to avoid splashing of brake fluid on wires in area.

The brake booster is what gives you power brakes. In the engine compartment in front of the steering wheel is a round black flat ball looking thing. That's the brake booster with the brake master cylinder attached in front of it. The brake booster uses VACCUM from the engine to multiply the force that your foot applies to the master cylinder. Used with power brake applications

What lines are attached to the master cylinder?

Brake lines and/or clutch line depending on vehicle. For brakes, the front brake lines usually attach to the frontmost connection, and the rear brake lines attach to the rearmost connection. Also of note, the front brakes typically connect to the largest of the two master cylinder reservoirs (normally the front one).
