brake pedal connected to the connecting rod for the servo?

air still in the system some where?

lid on the brake fluid?

something simple i reckon

2 things, air in the pipes, or calipers upside down.... are the bleed screws on the top or bottom part of the casting????

[sr nova boi]

Thanks for your help, the bleed screws are on the top part of the casting

[mowgli]

just keep bleeding them. if needs be, get an eezibleed kit from a motor factors.... they can be pigs to bleed thru

I had this problem on a mark 2 golf,bleed the rear drums/calipers aswell.

yeah is either air in the system or you have ****ed the master cylinder by pumping too hard or fast when bleeding.
there is a type of cylinder that is prone to failing on novas corsas annd astras but do not know the code.

poss EB or something on the cylinder

also had this problem. keep bleeding but i think not to sure but the pedal will always be soft to a point becaause of them master cylinder not being big enough ? correct me if im worng??

[dougie_boi]

did you fit the sprigs that that clip on the sides of the calipers mate. the ones that hold them down and stop the flex when you press the pedal

make sure all the assembly is done first, and when bleeding brakes always bleed the rear drivers side one firsth then the other drum then the front ones! and check so see if you can see any brake fluid anywhere!
