C172 Brake System

rickyrhodesii · August 23rd, 2007, 22:24

Could anyone elaborate or point me to a reference on the C172 brake system?

The only information I can find on the brake system in the information manual. I understand the 172's hydraulic system is comprised of a hydraulically-actuated brake on each main landing gear. You push on the top of either rudder pedal and the brake discs engage and slow the plane.

How much pressure can the system withstand? What is the normal operating pressure range? Schematics anyone?

Any help would be greatly appreciated!

Maybe ask in the Maintenance forum?

I can't clearly remember, but being AF maintainer, I asked this question during my PPL (2003). I THINK ... (don't take that too seriously) that the standard unpressurized (not supported by a pump) limit is 1500psi???

I know standard pressurized range is 3000psi +/-300.

I could be WAY off for a C172 though.

And I thought 1500 psi was the pressure on the gear when retracted for the cessna rg models...

See if you can find anything here:

I think it all depends mostly on how much you feed the hamster in luggage compartment #2.

Sorry - couldn't help myself!

Right...that probably would have been the best place to start!

Thanks for the responses.

If you're talking about a pressure range for 172 brakes, you gotta keep one thing in mind. The hydraulic pump is your foot. There is no engine driven hydraulic pump to keep the pressure in an standard "range". It's a very simple system.
