Air in Brake Fluid?

Check for corroded brake pipes as this will let air in,
Possible you have a leak somewhere along your brake lines also check seals in calipers for leaks!
Also dont forget to let your brake fluid stand for a while once poured into the top up reservoir
Also note that when bleeding its recommended that you do one front and the opposite back wheel then the front and then the back again! you cant just bleed the front wheels!
Also make sure you have the correct brake fluid!
