Hi all, I am trying to bleed my brakes (I have a K reg 205 XRDT base model front discs & rear drums), I have new brake components all round - new rear wheel cylinders, reconditioned front calipers and a new master cylinder. I have just bled the brakes once using a Gunson Eezi bleed kit, and the fluid came out of each of the bleed nipples clear with no bubbles. However the brake pedal still goes down to the floor. There is resistance but it is not firm. Does this mean there is still air trapped in the system somewhere? How can I get it out? I let the fluid flow through each nipple for a good while to make sure there was definitely no more air coming through. Could air be getting in somewhere?
The only thing I can think of is the bleed nipple fittings on the recon calipers which I'm not too impressed with tbh. When the driver's side caliper arrived the bleed nipple was already snapped off. The guy sent me a new nipple which I fitted but its not a normal arrangement, the nipples on the calipers don't go straight into the caliper they go through a bolt which is fixed into the caliper, presumably because the original threads on the caliper are damaged when the caliper is reconditioned, so they drill a new hole? However when I fitted the new bolt with the nipple fitting it doesn't screw tight into the caliper and stop , it screws up against the caliper and then spins. The passenger's side fitting doesn't spin. I wrapped the thread on the bolt with PTFE tape before I fitted it and it doesn't appear to be leaking but to open the bleed nipple you do have to hold the bolt with a spanner to stop it spinning. However, it does bleed and fluid comes through. Could this fitting be letting air into the system? I hope my description makes sense. Any advice greatly appreciated!
