Spongy Pedal Diagnosis
With this type of problem the most common symptoms your customers will complain of are : They’ve lost pedal height (sometimes called pedal reserve); or the brakes may feel spongy; the pedal may even touch the floor under heavy braking; or the brakes may not provide sufficient “stopping power”. Once the symptom has been verified, the next task is to establish the cause.
A spongy pedal is usually a sign of air in the system. Air may have got in through the because the fluid level is low. If this is the case, refill the system with the correct grade of brake fluid, then bleed any remaining air out.
