DI Brakes Just Not Good Enough

[jymmiejamz]

I didn't read all of the responses to this, but I will say that my wife's D1 came with brand new aftermarket pads and rotors front and rear that would barely stop the car. I got the Defender brakes parts from Zack, and now it stops like a modern car.

If the light is ON, check the codes. Unless you get 2-0, it should be fixable.

Other than a loose headliner, something odd with the radio reception, and a new coolant tank, this is the first issue this vehicle has had since I bought it about two years ago. So now I find myself trying to get back into the Disco I knowledge base, and I'm confused...... this is a 1998 HSE, and for the life of me, I can't find the OBD port that I thought they had in these later years. Am I wrong? I don't see a code display under the seat either.

I'm guessing it is actually a 'LSE' (HSE would be a RR).

OBD port should below the hinges of the fuse box covering. Down by the driver's shins.

Use these instructions to read codes. I'm guessing you'll need new sensors somewhere along the line.

Right, but.... not there. I tried to take a look up inside the dash to see if anyone disconnected it, and stuffed it up in there, but I can't find it.

The OBDII port is on a black trim panel. If that trim panel is gone, then someone probably shoved it up in there somewhere. I used to tuck mine into the trans tunnel trim.
I attached a pic now. I made a metal bracket because our stupid emissions testing required the plug to be secured. But otherwise it went behind where the yellow "arrow" is pointing.

 

[RBBailey]

I'll need to pull some panels apart to find it. Everything is pretty tight in there, as in, there aren't any loose wires that might have the plug at the end. And I can't see it from the top with the fuse door open. What color is the bundle of wires leading to it?

Flush the brake fluid. Brake fluid draws moisture and affects the compression of the fluid.

stick with burning people Dan. water does not compress and brake fluid does not compress. So mixing the two will not make a fluid that will compress.

you win the idiot award of the day.

fluid draws moisture. Moisture boils. Boiled moisture creates steam. Steam evaporates into air. Air compresses.

Your fluid needs to be changed/flushed every-so-often.

I don't think these brakes will get as hot as it does in your puzzle palace

Water ingress does indeed affect brake fluid performance in a number of different ways. It's one brake fluid's most noteworthy failings.

Yeah, that only happens on the space shuttle.

 

[discostew]

So this truck that can't stop is still able to make enough heat to boil fluid?

Yes, but that's not always what happens.

Water ingress can affect the fluid and system in a number of ways, depending upon what's used, how long it's in there, and how well maintained the system is.

This is not a new concept.

This whole place has become a fucking puzzle palace. All this off the wall bullshit is causing all these regular old problems. You guys are way overthinking this shit.

Are you sure you service vehicles for Land Rover?

As I mentioned earlier, this issue was part of the process of fixing the blown master. That is to say, I replaced the master, installed new (speed bleeder) valves, and ran a liter of new fluid through--twice. Once at once, the second time a few days later. This was one month ago.

The brakes just never quite returned to how they were before, they never were good, and I had planned to attempt to make them better. But now with the ABS light on, and the brakes softer than they were before the master blew, I'm tackling the issue little by little till it is solved.

 

[D Chapman]

Could be a bad master.

 

[discostew]

It's just not what's wrong with this truck. Yes brake fluid should be flushed.

 

[discostew]

Could be a bad master.

More than likely the pistons are getting seized in the caliper bores. If the pedal isn't sinking then the master probably isn't the problem.
