As friction linings wear down excessively, the caliper and wheel cylinder pistons must travel further outward to contact the friction surfaces, consuming extra hydraulic fluid volume from the reservoir and causing a low pedal feel. Alternatively, worn internal cup seals inside the master cylinder can allow brake fluid to bypass the primary piston under pressure, causing the pedal to slowly sink under steady foot pressure without external fluid loss.Brake pedal sinking lower than normal or requiring extra travel before slowing down? A brake pedal height inspection diagnoses low fluid, air in hydraulic lines, worn pads, and master cylinder bypass issues.
