A low or soft brake pedal may be one of the following. Check each one in turn:


Damaged brake hose


If any of the brake lines have been damaged in any way brake fluid can leak out or air can get in the system and will cause the pedal to feel soft, spongy or a long pedal travel. 


Inspect all the brake lines and replace any lines that are damaged.


Low brake fluid level


Check for possible brake fluid leaks, check all hose joints, master cylinder and brake calipers.


Check fluid level and top up if necessary. 


Fill to the marked line on the reservoir.


Contaminated brake fluid


In case of fluid contamination, drain all the brake fluid in the system and refill with new brake fluid. 


Brake fluid is hydroscopic which means its absorbs water from the atmosphere and must be replaced annually.  


Bleed brakes to remove any air in the system.


Worn brake pads


Check to see if the brake pads are worn down or damage. If so, replace pads. You can purchase Tomcar brake pads here.


Brake booster failure


Check to see if the booster has failed, if so, replace booster.


Brake pedal linkage


Check brake pedal for free play in the pedal linkage before pressure is applied to the brakes. 


If so, adjustment may be needed to the linkage between the booster and the brake pedal to reduce free play.


Brake pedal return spring


Check to see if the return spring is still attached. 


If so, check to see if the spring is worn. Replace if necessary.


Check brake calipers for wear or damage.


Check if the brake caliper slides are free, clean and lubricated.


Check the caliper piston for rust or damage.
