I have fitted my car with gold brembo calipers front and rear all bleed tidy and still my brake is sometimes going to the floor and a few pumps and it back ? do i have to upgrade the survo or master ?? any help would be very helpfull she is dew for mot.

 

You must still have air in the system somewhere,get plenty of brake fluid and keep toping it up as you go a long.I didn't have any problems when i done mine.where in south wales are you

 

either loads of air in system ( are the brakes spongy when they work?)

or,

master cylinder is not large enough and cant shift enough fluid to move the calipers.

worst case scenario the seal may have broken in the mater cylinder during the bleeding process as it is taken further down the cylinder than normal during bleeding. this happened to me on a crx once took ages to diagnose!
