Got an early X350 that has spongy brakes after air got into the system after changing rusty brake pipes. I've pressure bled it multiple times but think there's air in there still as pedal is spongy, I've got a monsoon adapter and V130 SDD but I'm struggling to find the brake bleed procedure/function in the software.

I've tried the spongy brake pedal on the symptoms sections but this doesn't bring up any brake bleed options.

Is this option on this version of SDD at all? I've spent hours on it to no avail!

Can anyone shine a light?

 

Guessing here however I was in jlr sdd yesterday and I believe I saw an ABS function.

IF you managed to get air into the ABS system you have to use software to actuate that before you can do a successful system bleed.

 

It is able to read ABS module but there isn't an option to bleed the brakes. I'm beginning to wonder if due to mine being an earlier than 2005 model that SDD doesn't offer this option. I'm wondering if I'd be better off using an older version that might enable this?

 

So what year is your car and engine and what version of jlr sdd do you have?

 

V130 and early 2004

 

Have managed to get my hands on IDS V125 (the Ford software) and set it up, but again cannot find a feature for brake bleeding.

Has anyone ever done this on an early X350 or other similar aged Jag via IDS/SDD? If you have I'd like to know how as it's got me beat at the minute!

 

The only special procedure mentioned in the X350 Workshop Manual for brake bleeding which involves SDD is using it to put the Park Brake into service mode.

Can't believe that a major motor manufacturer doesn't have a procedure within its diagnostic software for assisting the bleeding of the ABS block. Beggars belief!

 

They neatly deflect that with a NOTE in the procedure:




The procedure doesn't go into any detail about what to do if "should be adequate" becomes "doesn't".

Thanks for going to the trouble of showing me the document, much appreciated. For a major manufacturer that seems incredible! So it seems the only way to solve my spongy brake and long brake pedal travel is to keep bleeding until I'm blue in the face? 😡

 

Let me put my 2 cents in again here.

Normal brake bleeding does not get air out of the abs module IF air is in there and will result in a soft spongy feeling when pressing on the brake pedal.

I have not done it on the Jag however on my truck I had this problem and had to get a scan tool that was able to actuate the pistons in the abs module to suck in brake fluid.

I have to believe there is a procedure in jlr sdd to do this with the abs module.

I will look today.in V 131.

 

​​​​​​If you could that'd be really appreciated, it's getting frustrating!

 

Ok this is what I see using jlr sdd v131.06.

There is an abs configuration run option as you can see. No idea what it will do.

I do not want to run it as there is nothing wrong with my system and I do not want to risk anything.

Also when I last bled my brakes I did not get rid of a spongy feeling until I did a pressure bleed by applying pressure at the reservoir and then bleeding.

 

Oh and I sure know how frustrating things like this can be.

I am currently battling with my Range Rover electronic parking brake failure. jlr sdd has been very useful in identifying the issue and will be needed
to "reset" it.

At least the 2005 Jag has pads and not shoes which are such an antiquated design on an $80,000 2013 suv!

 

Sadly that just configures a new ABS module if you replace it. It doesn't give you any option to bleed the brakes.

 

Have you tried it?

If it does not actuate the pistons when configuring then it will not help however if it does it is worth a try I think.

Other than that I think you are left with the pressurized bleed technique which requires a pump plus an adapter that fits on the brake fluid reservoir.

 

Yes, tried it. I've done the pressure bleeding with the correct pressure bleed tool lots of times to no avail.

 

Oh boy. I can see why you are so frustrated.

I am out of ideas at this point.

Although a long shot I might be tempted to somehow "prime" the abs module manually. That is if I thought air was in it.

I wish you luck.

I was thinking that you do not show any abs faults which I would have thought you would if there was something wrong with the abs unit.

How about trying an emergency braking procedure to see what if anything happens with the abs being activated that way?

 

Well what I use to do was bleed the ABS on a gravel road?
Slide the wheels a few times and activate the ABS so it will pump the trapped air out into the hydraulics.
Then bleed at the wheels like normal.

Worth a try but as I found sometimes it made no difference in the feel of the pedal.
So I either did NOT have air in the ABS or it was something else causing it.

I have asked this question a couple times on this forum, and not only could I not believe that "a major motor manufacturer doesn't have a procedure within its diagnostic software for assisting the bleeding of the ABS block". I couldn't believe that the "Jag Techs" on this forum didn't know either. Well after doing some research, I figured it out. Jaguar did have it in their software, just not in plain sight.
I tried the following on SDD v125 and v131. It should work the same on the other versions as well. This is from v131
