When climbing, you would not be using the brakes, therefore it should not affect anything. Brakes fades when the fluids are not in good condition and repetitive use of the brakes causes the fluids to heat up resulting in brake fade.
With vehicle stationary, start engine and depress and hold the brake pedal. If it starts to sink after a few seconds, the brake master cylinder is leaking pressure internall and needs to be repaired or replaced.
