It won’t accelerate properly.

If the master cylinder is found to be faulty, it will need to be replaced and the brake system bled.

A mechanic can test the master cylinder for internal leaks or pressure loss. This may involve observing pedal return or using pressure gauges.

Install new brake pads and, if necessary, new brake rotors to restore proper braking function.

Visually inspect the thickness of the brake pads and the condition of the rotors. Replace any components that are below their minimum thickness specifications.

Air can enter the system through leaks. Inspect brake lines, hoses, and seals for any damage or wear that could allow air ingress.

This process removes air from the hydraulic system. It typically involves opening bleed screws on the calipers and master cylinder while a helper presses the brake pedal.

Thoroughly inspect all brake lines, hoses, calipers, and the master cylinder for any signs of fluid leaks. Repair any leaks found.

Locate the brake fluid reservoir under the hood and check the fluid level against the 'min' and 'max' markings. If low, top it off with the correct type of brake fluid.

A mechanic can use specialized equipment to pinpoint exhaust leaks accurately.

Inspect the exhaust manifold, pipes, and muffler for any signs of cracks, holes, or loose connections.
