That Guy Posted October 28, 2015 Share Posted October 28, 2015 Stopped at traffic lights today and while having my foot on the brake pedal it suddenly went soft for a few seconds and my foot sank then hard again (yes I am talking about the brake pedal lol) I have the red brake light lit on the instrument panel but thought this was due to condensation shorting in circuit board out (common in 03 focus models) I have checked the break fluid and it hasn't dropped at all. Discs and Pads are well within limits too. Anyone know what this could be? Quote Link to comment Share on other sites More sharing options...

That Guy Posted October 28, 2015 Author Share Posted October 28, 2015 When was the brake fluid last changed ? Would love to be able to answer that but not since I have had the car (3 months) the oil was changed in 2007 but only done 3k since so hoping then but not sure. I have just changed the engine oil at the start of the week. Would old brake fluid cause the light on the dash too? Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted October 28, 2015 Share Posted October 28, 2015 Brake fluid is hydroscopic - meaning it will absorb moisture over time - which lowers the boiling point - which can result in spongey brakes & reduced braking efficiency. I'd change the brake fluid first as it's the cheapest & easiest potential fix & doing that will also give you peace of mind & then see if the warning light stays on or goes off after the fluid change Quote Link to comment Share on other sites More sharing options...
MONDEO TXS 2.2 Posted October 28, 2015 Share Posted October 28, 2015 A picture of the warning light would be good Quote Link to comment Share on other sites More sharing options...
That Guy Posted October 28, 2015 Author Share Posted October 28, 2015 This is the warning light I have: Sometimes it goes out for a few minutes, sometimes the ABS light flashes too but not very often! Quote Link to comment Share on other sites More sharing options...
ippy Posted October 29, 2015 Share Posted October 29, 2015 when were the brakes (discs and pads) changed? I had a similar problem with my abs lite turned out to be dirty connections on abs wire going to sensor so cleaned them all up and changed discs and pads and I haven't had any problems since Quote Link to comment Share on other sites More sharing options...
