The restriction will cause slow release of the brakes

What is one effect a restricted compensator port of a master cylinder will have on a brake system?

C. Do not set parking brake when brakes are hot

Which statement is true with respect to an aircraft equipped with hydraulically operated multiple disk type brake assemblies? A. There are no minimum or maximum disk clearance checks required due to the use of self compensating cylinder assemblies. B. No parking brake provisions are possible for this type of brakes assembly. C. Do not set parking brake when brakes are hot.

Reduce the pressure to the brake & increase the volume of fluid flow

Debooster cylinders are used in brake systems primarily to.....

Worn brake lining

If it is determined that spongy brakes action is not caused by air in the brake system, what is the next most likely cause?
