Leak Checks

It is possible that all evidence of fluid leakage may have washed off if the vehicle has been operated in rain or snow because brake fluid is water soluble. Refill system, bleed and apply the brakes several times. Examine the system to verify the brake master cylinder reservoir fluid level is actually dropping. Locate and correct the external leak. If fluid level drops and no external leak can be found, check for a master cylinder bore end seal leak.
