Brake Woes

[spizzak]

Hey guys, I've had some brake issues for quite a while now and I'm finally breaking down and asking for help.

#1. Brake light came on (I think it was due to low fluid level because of what happened in #2)
#2. Left rear caliper seized and brake pad wore down to the metal and took a bit of the rotor with it too.
#3. Sometimes ABS light came on as well but sometimes it was off
#4. I replaced both rear calipers + pads + rotors and cleaned out all the metal filings that had accumulated due to the metal-on-metal action on the left side.
#5. Brake + ABS light still on- read the codes - both pointed to left rear abs sensor.
#6. Replaced left rear abs sensor with one from ebay + reset the error
#7. Everything looked okay for a week - now the abs light and brake light come back on every once in a while with the same error codes as before.


That's about all the info I have. Let me know if you guys have any ideas on where to go with this next or if I left anything out.

Thanks!

when you reset the cel did you clear the stored history? thats my guess.

I just used the "Pump the brake 10 times" method. Is there something else I should've done?

Nope, that's the way to do it.

Did you test the old sensor before replacing it? The test is quite simple: hook up the sensor to a multimeter (set to AC volts) and spin the wheel, if the sensor output voltage is between 0.25 and 1.2 volts then it's still good. If the sensor isn't mounted close enough to the sensor ring then the output voltage won't be high enough. So if you're on the low-end of the scale, try adjusting the position of the sensor (I know, easier said then done).

FYI: My failed sensor was reading about 0.1V which is nowhere near enough.

Also, be sure to use the lowest possible voltage range on your multimeter to get the best possible resolution.

Thanks I'll give that a shot.
