I have Suzuki Swift dlx 2010 around 117k on odometer
I have a brake issue with my car. Sometimes driving on a plan road suddenly brake pedal become soft and spongy. I have checked all wheel brake cylinders,changed the Mastercylinder,also bleed the brake oil but the problem as it is..
This problem occurs once in a month and after pumping the pedal 3 to 4 times the brake work normally..
