It's been into the garage because when she turns left her brakes fail. Doesn't do it going right handed. If you put your left lock on an reverse there's no brakes. Before they fail there's a banging noise. The brake fluid level is on max and there are no leaks anywhere. The discs pads and bearings are all fine. There's no play in either of the front wheels. The servo and the master cylinder are all ok according to the mechanic and he has not come across this before. What he did do was fill to the brim with brake fluid and it stopped doing it for a week. The levels are still at max but it is occurring again. Can anybody work out what the problem is as Citreon have no idea and say it's not a manufacturing fault.

When turning left or right on full lock the drop link lower ball joint where bolted to the anti roll bar, the threaded section pushes against the back of the calliper pushing back across which forced the piston back into the calliper causing the pedal travel. Of course as the pads and disc wear the calliper will move closer to the drop link connection making the pedal travel worse. Replace the pads and it will go for a short time before the fault returns. It will be very close but not quite touch when stood still with the cars weight on the suspension, but as you move off the car will rise at the front causing the anti roll bar to move on the ends and will make the threaded section of the drop link to push against the calliper. Take vehicle to your dealer to get this sorted out as is a very serious design fault and needs to be sorted out. If we all do nothing then no issue for Citroen to sort out thus no safety recall.
