Dog chewed brake lines

I think $750 sounds fair for what is being done. Here in the San Francisco area it would be nearly half as much more. Labor rate here are sky high.

 

Is Fluid Film a deterrent?

 

Its amazing how people just post things with such confidence when its 100% incorrect. Sure if you extended the wire by +30 feet it might cause issues but with proper connections it would cause zero issues. 18 gauge copper wire has 6.385 ohms of resistance per 1000 feet. At 10 feet its 0.064 ohms, assuming you added a foot when you spliced it would be 0.07 ohms. Literally 0.006 ohms of a difference.

ABS sensors (at least modern ones) are active, meaning they need power to function. A voltage is applied to a sensor, this sensor reacts when metal is passed near the sensor. This creates a square sine wave of a few volts difference between the highs and lows of the pulse wheel. The ECU/ABS control module is reading the frequency of those pulses to determine the speed of the wheel, it is not measuring resistance. You cant even test an ABS sensor using ohms, in fact you can potentially destroy a sensor using a multimeter on ohms. This is because the voltage a multimeter deploys to a circuit to measure the resistance can be harmful to these types of sensors. The only way to tests these sensors correctly is to use a voltage and measure the pulses either by using a scan tool or setting the sensor up with a scope.

That being said even if you added 30feet the resistance over the entire wire is consistent, meaning the pulses will still be shown to the ECU just at a slightly different voltage. It just depends on how tight the voltage tolerance is on the ECU programming before it throws a code for a faulted sensor.

Boom! Hats off to the electrical wizard.

 

It's funny they do something like that and you still have to rub them on the head and tell them it will be ok .

 

I'm not sure if Fluid Film is a deterrent, no experience there.

 

Thanks, now this makes sense. For the life of me I couldn't figure out why Toyota would have that wire so exposed if the resistance was so critical to operation. I would have just spliced it, replaced the brake hose, and told the dog he was naughty. That said, I also understand having it put back to the condition it was in before the doggy taste test. I just cringe when anyone else takes a wrench to my stuff.

 

Picked the truck up today, everything is back to normal except now im getting vibration in the brake pedal from the brake booster. Used to only feel it slightly at startup with my foot on the brake. Now it’s stronger. Im assuming from the brake fluid flush. I had the dealer look at it before I left and they claim that its possible it got to low on fluid and fried the pump. Doesn’t sound right to me. I had a 240 mile drive home and it got less noticeable over the duration of the drive.

 

anyone remember the post from the dude that's dog chewed the crap out of all the wires in his truck?

 

This sounds like air in the acumulator/ABS valve assembly. It will probably work out the rest if it seems to be getting better. Does this happen only at startup or while you are driving?

 

Appears to be a few threads.

The dog didn't get sick or anything from any brake fluid I hope?

 

Happens more on start up but also while driving. I had someone pump the brakes and make it happen while i was looking and saw air bubble up into the reservoir.

 

Dog was fine. It didn’t phase him.

 

If the OP has them change his spark plugs at the same time he might just get a whole new truck outta the deal...
