Re: Bleeding Brake Problem
FORScan would be more suitable.

Re: Bleeding Brake Problem
I'm actually wondering if the bluetooth will reach to my computer, it's right next to the driveway very near. I have a cheap bluetooth obd2 scanner and i've been using Torque on my phone.

Did you try switching the ignition off and one again?Ashman wrote: ↑Thu Apr 18, 2019 1:02 pmThe abs and tc lights are on but i did think that could be because we've been fiddling with it on axle stands. I suspect they will go out (hopefully) once it's driven. I scanned for codes but all i got was a U0073 so i think my reader may be complete sh*t. I did try turning the steering lock to lock a few times but it didn't work.
The ABS light only goes out the second time after the battery has been removed or the abs wiring disturbed.
U0073 is usually associated with a bad connection on the ODB2 port, either a bend/pushed-back pin or not fully plugged-in.

Re: Bleeding Brake Problem
Is it locking up, or is the ABS just activating unnecessarily on that wheel? The Elgrand was doing this the other day and I suspected a sensor problem. I was sort of right -
As soon as you touched the brakes the ABS logic saw no wheel speed and assumed it was locked, triggering the brbrbrbrbrbrbrrbrbbrbrb

Re: Bleeding Brake Problem
I've seen similar symptoms from great blobs of copper grease that have found their way onto either the sensor or the toothed wheel.

Re: Bleeding Brake Problem
I fitted the hub today and tested the brakes and it's still locking. So it's definitely not the sensor, as far as i'm aware there's no ring on the front either.

Re: Bleeding Brake Problem
I don't think you can see the sensor ring on the front.
What do you mean by "locking". Are you driving the car, applying the brakes hard, then finding that the front left wheel will lock up and skid?

Re: Bleeding Brake Problem
Not driving fast, just 1st gear off the driveway. The front left wheel will instantly lock as soon as the pedal is pressed with any force. The sound it makes is a telltale sign that it's locking, in fact it's exactly as Phil described above.
I think the sensor ring is inside the hub with the sensor.

Re: Bleeding Brake Problem
You can do a test...voltmeter on ac...connected at abs plug....
Not spinning 0v...spin wheel you will generate an ac voltage someyhing like 0.250v ac...
Better desc. online but can show signal good or bad from sensor or reluctor ring.

Re: Bleeding Brake Problem
If you are going fairly slowly then ABS doesn't work. Below about 5mph the sensors can't work out the true wheel speeds, so the ABS turns itself off. This may not be what you are describing, but I thought it was worth mentioning.

Re: Bleeding Brake Problem
Yeah need to be reading above 10mph on speedo for abs to reset and kick in.
Similar to when youve been working on a car and rotated a wheel with ignition on..will register a fault and then need x4 correct inputs to determine ok and reset and turn light off...pull the abs fuses...still locking not abs...

Re: Bleeding Brake Problem
I'll check it with the meter tomorrow, also fuses.
If not abs then what's likely to be the problem, caliper?

Re: Bleeding Brake Problem
when you say "locking" is the wheel actually stopping turning and stalling the car or dragging the wheel or just making the locking noise?
When backing my previous car off the drive when on lock then it used to clunk a couple of times and I was advised this was the ABS checking and setting itself. Can you continue to drive the car after the wheel "locks"?

Re: Bleeding Brake Problem
The wheel is actually locking up and skidding when braking with enough force to stop the car as normal, as in without me stamping on the pedal. As soon as you take your foot off the brake it will move fine. I'm able to spin the disc by hand so it's not locked.

Re: Bleeding Brake Problem
My guess, and I stress it is a guess, is that the only thing that could lock one wheel would be the DSC system.
For certain though I have no idea how you go about diagnosing and rectifying that if it is!

Re: Bleeding Brake Problem
The battery is shot so I'm gonna wait until the new batt is here before fiddling with it anymore. Well, that and I have an overwhelming urge to hit it with a hammer.

Re: Bleeding Brake Problem
really stupid question and probably answered before but what tyres are on the car?
my first Rex came on rotalla ditch finders and would trigger the ABS when under normal breaking conditions.
