A change in the feel of the brake pedal is a good indication there’s a brake problem. Therefore if the pedal starts to feel soft (or worse, contacts the floor) do not drive the vehicle without first having it checked carefully by a qualified brake technician. Because loss of pedal ‘feel’ can indicate a very serious problem with your vehicle’s brakes which may result in sudden and unexpected failure.
Noisy brakes can occur for many reasons. Squealing can occur due to brake pads being worn through to a stone being lodged between the disc and the rotor. Hence, best to have a qualified technician inspect the brakes as soon as possible.
If your brakes are vibrating when applying them this may be caused by the disc pad or rotor having an uneven surface. Inspection by a qualified technician is required immediately.
