Kia Maintenance Questions? Ask a Mechanic for Answers ASAP
Hopefully i can help..
Is this actually felt through the pedal itself or via body/floor of the car - what rate is this knocking, once or twice per wheel revolution or?
Apart from the front discs/pads - has anything else been inspected so far?
Hi..there thanks for your reply..
Ok..its good that you have ruled out the rest of these areas - to me by experiance recently on another car we had in with the same issue was found to be broken target ring for the ABS sensor on the driveshaft,this didnt bring up the ABS warning either but was felt on the pedal like a vibration,knocking or kicking back..sometimes these small cracks on the target ring cant be often seen due to corrosion etc that builds up on these..so it would certainly be worth checking those..from i recall on these cars the ring is on the driveshaft outer cv thats goes into the back of the hub ..its like ring with teeth all the way round.spray with some brake cleaner all the way round,wire brush and check each tooth gap carefully for any small splits or cracks you see on the ring as you slowly rotate the driveshaft - you will need to check both sides,drivers and passengers - if you do come across a broken ring then the best idea or cheapest way forward is usually another driveshaft or cv end joint with the new ring on it ensuring it does have the same amount of teeth as the old one..So as above have a check of these next..i do hope this helps
