Yeah, I just went out now to check over everything after it being left overnight. No fluid leaked out anywhere I can see and the brake pedal still feels the same so I’ll call it good for now.

Thank you all for the replies! I finally got a chance today to have another go off it. So to answer your comments first. Yes, certainly got air in the modulator, I bought a 5l drum of brake fluid so no issues there. Don’t have an easy bleed kit but I was able to get around that, will detail...

Yes, they were reading it and doing the pumping/ignition when necessary. Honestly after thinking about it for a few hours, im hoping that maybe since we were doing all the bleeding over, and over and over again, that the brake fluid was starting to get aerated and would never bleed out...

Good idea, even though they are tight they may not be sealing correctly.

I agree, this is probably the best course of action. More than likely has to be a leak, I was just hoping it’s not a modulator off job as I’ve done it in the past and it’s not fun. Hopefully something shows itself, otherwise I think I’m going to try bleeding just the reservoir only, lower...

Yeah, I only wanted to mention that I did it before as I understand one of the most common problems is people don’t follow the procedure and then come crying for help. I’m certainly doing all the nipples in the right order, and I’ve double checked they’re all tight. Fluid level always kept...

Hi everyone, Just going to make this quick post before I completely lose my mind (already lost it in the garage and brake fluid is now everywhere) Reviving a 1998 4.6 P38, been off the road around 12 years. Brake calipers were sticking, as preventative maintenance I have replaced all the...

Brand new accumulator sphere less than 12 months ago, as I said in my first message I swap this new accumulator sphere onto whichever pump I deemed best looking. Yes, full complete brake bleed following rave procedure. Yes, I do know that’s the case, the thing is that at the end of the...

Thanks guys for the information, very helpful at usual. I actually after making this post made an adjustment to my ABS system, when I replaced the modulator and bled the whole system I had overfilled the reservoir (well I had to keep topping it up for bleeding but it was overfull by the time I...

Fair enough, any idea what I should look into replacing or checking first? I’ve kinda gone through the whole system but obviously all my used parts are 20 years old now (at best) so it’s not a guarantee they’re working at their best. Are you making your assumption based on the time it takes to...

Yes, the whole thing with all the switches attached to it. Basically the whole unit, I have four of them complete and I just swapped my new sphere onto which ever one I deem to be the best.

How long does the pump run after ignition off for one hour? = 15 seconds How long after overnight? I cant give you the most accurate reading as I would have to leave the car sit overnight for that one, but from memory its under a minute, possibly around the 40 second mark from a time ago when I...

Hello everyone, I seem to have a common theme with a lot of my posts, and that’s that they are mostly related to the ABS system on my Range Rover. Just to recap - 1999 P38 2.5 DSE Car has: New abs pressure sphere Good used abs pump (I have about 4 to choose from and have swapped them around...

Hello everyone, Just wanted to write the finishing post for this thread, now well over a year later. After checking all of what I would regard as "basics" - stuff that doesn't involve completely ripping into the ABS system and getting brake fluid everywhere - such as sensors, ecus, wiring...

Yes, I was inspecting the one I had removed, I can see that the bottom panel looks like it comes off easy. Can the bottom be removed without putting anything out of place? Does it need to be sealed up again with some kind sealer? I guess I would just have to decide whether I attempt to remove...

UPDATE. It has been almost a year… I am updating this for future reference in case any other poor soul happens to have a similar problem, only to find this post and see that there is no conclusion! Note: my problem is not fixed yet, I just have hit a major milestone allowing me to actually...

OK, I just stopped being a wuss and did it, i adjusted the mid section of the pump towards the front of the car. Fuelling now up at around 5mg/s instead of 0.25mg/s. Idle is super smooth and after a quick rev it returns to idle quickly and smoothly with no lumpyness or missing. I do all this...

I do have a compression tester, I might just have a couple more goes at adjustments first before I test the engine for that kind of a problem. I have driven around 10K miles since I got the car about two years ago, it doesn't seem to have any of the normal symptoms of low compression or head...

Hello everyone, I have been working on my P38 to try and make the engine run as it should pretty much since I got it. Its had a heap of work done to it - summarised below: Full service of every single oil and filter in the vehicle Refurbished injectors x 6 Intake manifold gaskets (1999 model...

I believe it is reading correctly, I have very slightly "overheated" the engine twice in my ownership (Once with viscous fan explosion, other time just with a massive air bubble in the system) - Both times it only went about one notch over the middle of the gauge so I believe that - if it was...
