what now !!!!!!!!!!!!!!!!

[hiline]

ok guy's the wife's ABS and TC lights are on in her 97HSE 8O 8O


also the brakes have faded :cry: :cry: :cry:


why does everything go wrong at bloody christmas time :evil: :evil: :evil:

[Slunnie]

If its anything like the Disco2, it'll be the ABS sensors. See if it clears, and also probably try new pads that dont squeel.

[hiline]

just had my personal mechanic here https://www.aulro.com/afvb/ https://www.aulro.com/afvb/ https://www.aulro.com/afvb/


bad news, the fault wont clear :cry: :cry:


loss of pressure in the system 8O 8O looks like it might be the brake booster

[DEFENDERZOOK]

<span style="color:blue">did they run an accumulator in 97...?



a black pressure bulb thingy on the box with all the spaghetti plumbing....</span>

<div class='quotetop'>QUOTE</div><div class='quotemain'>a black pressure bulb thingy on the box with all the spaghetti plumbing....[/b][/quote]

i think so


it has brake fluid all over it :cry: :cry:

[DEFENDERZOOK]

<span style="color:green">the diaphragm inside may have died....


it has a rubber diaphragm inside with pressurised gas on one side and
pressurised brake fluid on the other side.....
the pressure in the brake fluid(built up by the abs pump) gives a higher pressure
than in the gas chamber side....this is what gives you stored boost for braking
assistance....</span>


<span style="color:blue">
after switching the engine off....how many pumps of the brake do you get
before it gets hard to press....?</span>

In the P38A, the accumulator is screwed into the brake pressure pump - unlike the classic where it is remote.

Replacing it on mine fixed my brakes but that was different by the sound of it.

On mine, the brakes would take up to 45 seconds to reach pressure. If I used the brakes before that, it felt like there was no boost and the car was bloody near impossible to stop. I'd knocked over a few garbage bins and hit a few fences when I'd tried moving the car before brake pressure was available.

The accumulator has about 100 Bar (1500psi) or more pressure inside, so if the diaphragm split, I would think the nitrogen in the accumulator would pump brake fluid out of the reservoir.

Ray says there's fluid over the accumulator. Unless it unscrewed, I can't see how that would happen unless fluid spewed out of the reservoir filler cap. (There was a recall for the filler cap to be replaced. Mine was done a while back but I don't know why.)

Ray, is the brake pump running? You should be able to hear it. You can check how long it take for the brakes to reach full pressure by watching the red barke light on the dash. But the hand brake also operates this light so you'll have to release the hand brake for the test.

1. Release the hand brake
2. Start the car
3. Time how long until the brake light goes off. It should extinguish in less than 45 seconds. If not, your brake pump or accumulator are probably shot.

gee thanks for reminding me :cry: :cry: :cry: :cry: :wink:

[DEFENDERZOOK]

<span style="color:blue">go out and do some diagnosis tests and get back to us.....


we need to get to the bottom of this.....</span>

[hiline]

ok i'll go out and give what ron said ago https://www.aulro.com/afvb/

back in 5min :wink:

[hiline]

ok teast complete https://www.aulro.com/afvb/ https://www.aulro.com/afvb/ :wink:

the ABS HANDBAKE TAC lights all stay on


then pumped the brake pedal around 40times and still no pressure on it


does this help you zook https://www.aulro.com/afvb/ https://www.aulro.com/afvb/

[DEFENDERZOOK]

<span style="color:blue">when you turn on the ignition can you hear the pump run for the abs.....?


if this is not running it may even be a simple fuse....</span>
