couple wks ago my abs and parking light came on...
so no abs... fun.. not. haha
before the light comes on after starting the truck, it takes about 2-3minutes for the lights to come back on, but in that time, when braking i can hear a ping/clank sound and feel the brake pedal puslating, it sounds like the tick/ping sound from the show Wheel of Fortune, its a slow tick/ping.

any idea of what could cause this?
my brakes still have some life left on them, i will replace the brakes and wheel bearings next month probably and get the rotors resurfaced, but i am still curious as to what is causing this problem....
i really cant afford to take it to a repair shop right now, so unless it is something i can trouble shoot myself, i will keep driving with no ABS

 

it sounds like a speed sensor issue. if the light doesnt come on if the vehicle is parked, but then does once you have been driving it is usually due to the sensor intermitantly sending a erroneous signal. You have to get the computer scanned to find out which one.

 

It could be a sensor problem or a problem in the ABS unit it self. I would get it scanned to see if there are codes in the computer. There probably are.

 

Do a simple check of the brake fluid and see if you are low.

 

maybe hooking it up to a code scanner it might tell you what sensor or if its the unit causing the problem

 

very good point seen that happen before also

 

brake fluid is good, i hooked up a scan tool my friend has and no trouble codes where stored.
ive taken one front wheel off to inspect the brakes a bit closer and there does not appear to be anything broken, i cleaned all the dust/dirt off the front abs sensors and ring on the rotor.
next 3day weekend i get ill throw it up on the lift on base or take it by the motorpool and see if they got any high dollar scanners

 

Motorpool? are you from Europe?

 

Its the salt air.

 

it must be the sald air cuz i have a 2000 3.0l auto thats doing the exact thing but ive changed my rear abs sensor on differential but... the air realy isnt that salty here... i live on the river about barely half a mile from mobile bay... anyone have any other ideas... its not the brake fluid... or the abs sensor... or am i supposed to reflash my computer after i change the sensor?

 

salt air? how would air make a ticking sound?

 

make sure none of the teeth are missing or any slight cracks in the tone wheel?
how long have u had the 33's on? did it come on shortly after u changed tires? that could be throwing it off as well.

 

took it to the dealer the other weekend. its the rear sensor and the guy said that the teeth on the gears are broken as well. so i am going to rebuild the rear end soon i guess.
if the tone ring is also damaged, how much does a new one cost? and can i purchase just that part?
