husoi Posted February 29 Share Posted February 29 Poor bleeding? Assuming the pads are new as well. Unless there is a leak, which would leave a poodle on the floor I would go for air in the system 1 Quote Link to comment Share on other sites More sharing options...
RideWithStyles Posted February 29 Share Posted February 29 get a different mechanic to look at it might be best. not working as in?? lever moves freely when applied and released with "little or no artificial resistance? or is there resistance in a direction? but no pressure is going to the callipers or not the pads? Look at the master cylinder, is the piston seal good. has the rubber cap/seal on the master cylinder been sucked down? it should be flat every time... 1 Quote Link to comment Share on other sites More sharing options...
fluffy Posted February 29 Author Share Posted February 29 Thank you for the reply. As far as I know there is no air in the system and the pads are engaging but it won't fully engage on the brake disc they are all new parts I've even had a new disc on aswell but still nothing..thank you once again for the help Quote Link to comment Share on other sites More sharing options...
RideWithStyles Posted February 29 Share Posted February 29 braking systems are very simple in there basic form.. the other thing is is the brake system abs... if so check the fuses, relays and the abs pumps are a git to bleed. Quote Link to comment Share on other sites More sharing options...

RideWithStyles Posted February 29 Share Posted February 29 right easy then. so start at the first point. fluid and res, lever, master cylinder, hose, lever, master cylinder, hose, caliper, pistons, pins and pads.. Quote Link to comment Share on other sites More sharing options...
