7up Posted December 30, 2007 Report Posted December 30, 2007 Hi all and a happy new year, I have a little problem with the breaks at the moment and was hoping someone can help. I booked the car in for a service and was told that the front discs where warped and need replacing. I didn't have them done at fords but at a Tyre and break place in Dagenham called Elites. I did notice before having them done that now and again when pushing the break pedal that it felt like nothing was happening and that you wasn't going to stop, so i was hoping that when i had them replaced this was going to stop, but its still doing it. It happens more when going slowly and when i go to stop at a junction or roundabout. The rest of the time they are fine like they are working properly. I had the discs and pads changed, i have had a look at them and noticed that the discs have score marks on them and i get some squealing when stopping, do you think these disc might be warped as well. thanks peeps Quote
djx Posted December 30, 2007 Report Posted December 30, 2007 i might be wrong but the fact that it happens at low engine speeds sounds like an air/servo leak or something rather than the physical pads/discs. at low engine speed the assistance from the servo is less than at high speeds, maybe its too low to stop the car, if you had ever driven an old car without a servo then you would probably understand me a bit better, john.

sanjsanj Posted December 30, 2007 Report Posted December 30, 2007 tell ya what, with the engine off, keep pumping the brake pedal untill it gets rock hard. Then, with your foot firmly on the pedal, start the engine and the brake pedal should move down within a second or so. If it doesn't, its defo the servo gone. For comparison, you might wanna try it on someone else's car as well. Quote
Beyond Help? Posted January 4, 2008 Report Posted January 4, 2008 (edited) Check your vacuum pipe from the pump at the front of the engine back to the brake servo, it likely has a small hole worn in it at the engine cover or where it passes over the engine bracket. This loss of vacuum will be insignificant at high revs but cause problems at low speeds and if the brakes are re-applied soon after previous use. Edited January 4, 2008 by Beyond Help? Quote
