Narrative:

While rolling out after landing the brakes were applied to further slow down. Immediately upon application the left brake locked up causing the aircraft to go on its nose. The subsequent propeller strike damaged the fixed pitch propeller beyond repair. The flange was not bent. The cowl an spinner were untouched loose brake pads are the suspected cause.
