My ABS and TC lights are both on. The first came on and I figured my brakes needed changed, however after the change, they both still come on, and my brake pedal rubs, like it won't stop.

I would disconnect the negative cable on the battery so it can reset the abs module, on these cars when you change the battery you need to have a 12 volt supply connected to your lighter before you disconnect the battery so there will be no reset on any of the modules in this vehicle.. if that don't do the trick you need to scan the abs system to see if you have any hard codes or just to reset it with the scanner.. abs is for antilock brake system and tc is for traction control they both work out of the same module

make sure your sensor is aligned properly check your connections have you driven the car since you changed sometimes you need to drive the vehicle to reprogram the speed sensor into the abs circuit these are fused circuits check your fuses

ABS = Anti-lock Brake System.
TC = Traction Control System (Engine Control Module).
If the ABS lights on the dashboard permanently the ABS system is faulty. You must access the ABS & TC Electronic Control Units (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ABS ECU, in other words reset the ABS system and turn off the warning lamp on dashboard.
I suspect bad brake pedal switch, but you should scan the ABS & TC ECU's.

Speedo and traction control; check wheel sensors all 4, clean and blow the sensors and reactor rings.
Is ABS light on as well? if so, you need a EBTCM module mounted to the brake ABS pump facing the battery. There are places in the US that rebuild them with warranty for under $150.

when you have antilock "problem " on this vehicle you automatically get t\c light, I fixed this problem for a friend when the tire rubbed through one of his abs sensor cables .. just re-connected it don't spend $500 at a "RELIABLE" shop if you can fix this yourself....they will never tell you how easy it might be to repair!!

Hi,
Change the switch - it's above the brake pedal. That will probably account for the ABS light and the brake lights being stuck. Note that you may have more than one ABS issue, and if the light stays on you'll want to have that system scanned by someone with the proper test system for that reason.

i have had this a couple of times, when they have diff trouble etc i take them to a place covered in shingle on concrete. when i figure of eight them around so everything is working hard i can detect which diff or what ever is wrong.
now when u do this for a certain amount of time, (some differ) u have to understand what happens, when round a roundabout, the wheels closer to the roundabout are turning slower, outter wheels faster as they have further to travel, this abs traction control are programmed to see it.
when u figure of 8 it gets mixed up, i have had three now had them reset and bingo. I know your abs sensors are fine as light goes like u said. the most expensive bits are working.
also i would like to add, i changed a battery on 1, the owner claimed the same prob. u have to bear in mind she could be pulling a fast 1. anyway i had it reset at my own expense as could not reason with hear, it was cured.
so there is other things there somewhere that up sets it, if u keep on figuring 8 it this does.

I have a 2000 Catera that when I changed the electronic brake control module all warning lights went off, speedo and odo worked. New EBCM is $2000 Cdn I got mine used for 170. also it can be re built at modulemasters.com for $160. Not sure about the dash light tho.
