hi guys the other day i noticed that the driver side brakes are not connecting with the rotors real well both front and back so i pulled the calliper off the front then ran into some trouble with the piston jamming so i disconnected the brake line off the calliper and got the piston back down in the mean time all the brake fluid had leaked out of the calliper where i disconnected it, then i reconnected the brake line back to the calliper and topped the brake fluid bottle right up then procceded to bleed the lines left rear, right rear, front left, and front right but now the pressure builds up and the pedal slowly drops back to the floor?????? now im hoping that its just a case of i should have filled the calliper back up before reconnecting the brake line????as there would have been a huge air gap in the calliper but i thought bleeding would eliminate that but any help would be appreciated as she's off the road till i can sort this out. the thing is the pad is working better, pressure does build up but then drops away and pedal goes to floor do ya rekon its due to me not filling up calliper before reconnecting brake line or another fault my magic fingers have created lol
