Makes sense but if they were so bad there is a very noticable difference in peddle feel. Would there not be other issues while driving .

That will only have a momentary effect whilst it centres the discs. OP says peddle drops to the floor - that's an hydraulic failure. There is either air in the system or more likely a fluid leak. You push the peddle and the system pressurises. If the peddle is then dropping, the pressure has been lost. It's a closed system, so either the fluid is escaping somewhere causing the pressure to drop or there is still air in the system.

This is definately a strange one, i will say the pedal doesnt drop completely to the floor, just more than your average press, again only when on full lock. I definately have no leaks, i would also like to think no air was in the system having been bled so many times More of an update..... ive got both hubs off today, they were slightly noisey/rough but no play what so ever, and spun quite well ! Hub nut was tight on also prior to removal.. |

Its definately nearside, just couldnt pin point front or rear. |
find a 32mm socket and see if any of the large hub nuts tighten up any,
start on the front N/S. |

Are the brake lines twisting during full lock and stopping the fluid to the calipers?

Just to update this thread.
Fitted new front wheel bearings, ball joints etc pedal no longer drops when on full lock. The pedal is now at a point where it drops slightly /mushy on first press, solid on second press...So air still in system somewhere. I may end up changing MC next along with new end brake lines and fittings for the rear (fronts are in excellent shape) Any thoughts? |
On a side note, is their a procedure for purging ABS?

Change fluid/bleed brakes. Go for a drive and engage ABS - find some loose gravel or such to brake on. Re-bleed brakes.
https://www.google.co.uk/url?sa=t&rc...oJ2lNTvJ5NMT4A Particulary this section Commanding Sequence Control Without the Select Monitor You can also command Sequence Control without the Select Monitor. To do this, with the ignition switch “Off,” ground terminals 3 and 6 of the diagnosis connector, using the connector’s grounding wires. Turn the ignition switch “On” and, within a half second after the ABS warning light goes off, depress the brake pedal and hold it. The ABS will go into Sequence Control and purge air from the HCU. |
