Simply_Graham Posted July 12, 2007 Report Posted July 12, 2007 Hi I had an odd thing happen yesterday, initially the traction control lamp lit but went off after half a mile or so. A mile further on it felt like I had the handbrake on when I pulled away (I did check) several hundred yards further and the car brakes appeared to be on; the brake pedal was near rock solid.I awaited recovery during this time any pressure must have dropped in the brake system, I was escorted home and the same happened on the way home. The RAC think it may be the master cylinder; however the brakes are being applied for me not by me... I Quote
west Posted July 12, 2007 Report Posted July 12, 2007 I did change the front pads about 5-6 weeks ago, and have now seen the advise regarding flushing the older fluid out rather than send it back through the ABS modulator. Probably put something back wrong or broke something in the process. ABS works by releasing the brake pressure, not increasing it, so its unlikely to be this. Quote
Simply_Graham Posted August 3, 2007 Author Report Posted August 3, 2007 The answer... Debris from Master Clyinder causing a problem with the Brake release valve in the ABS/TC/ESP modual. Flushed all valves through with brake fluid (off car) re attached Controller (with all the valve body controllers built in)refitted, bled brakes, reset DTC No problems since... Brake pads were not fully retracting due to risidual brake line pressure, and still rubbing against the discs, as these and the pad warmed the friction co efficent of the pad material increases feeling like the brakes are being applied, they would eventually fade, as they become too high in temperature.

johnswlondon Posted August 6, 2007 Report Posted August 6, 2007 when you change the pads on abs eqipped cars dont you need a brake winding tool and to open up the bleed screws at the same time? Quote
Tommie1 Posted August 6, 2007 Report Posted August 6, 2007 The traction control could apply the brakes. Are you sure you did not touch the sensors for the ABS - ESP -Traction control?To be OK, they should be as close as possible to the toothed wheels. Quote
johnswlondon Posted August 6, 2007 Report Posted August 6, 2007 ok,heres the brake caliper rewind tool you are supposed to use.if you just squeezed the old pads on,the abs thought the brakes were locking hence he abs cutting in http://cgi.ebay.co.uk/Ford-Mondeo-Galaxy-R...1QQcmdZViewItem Quote
