Thread: Defender Xtreme brake bleeding (ABS)

mod the bracket while you are at it.....FWIW pretty sure early defender were the same set up.

I had to disrupt the brake lines a while ago myself, and came across the stupid bracket design. I plugged the lines when I disconnected them, then modified the bracket (just needs a slot cut in it to the hole, if I remember correctly?). I was expecting to have issue bleeding when I reconnected, but I didn't seem to get any air in from the reconnection process (or not enough to make a difference, and it travelled up by itself).

so long as you have not permitted air to get in above the ABS module or allowed the fluid to drain from the abs module then you can bleed the caliper as per a standard brake system providing you do not allow air to enter the abs module while bleeding.

Yes, the bracket's a pretty stupid design. Even if one slots the hole so that the caliper can be hung up, the metal brake pipe is rather more vulnerable than it is with the old design.

I'm not too concerned about it this time though, as I want to run some new fluid through the system.

Yes, that seems to be the important point. I am going to clamp the brake hoses to prevent fluid draining from the ABS module, as it looks like a PITA if you have to bleed that.

This is not really my main concern, but point taken.

They have changed the run of the tubing with the later models, which makes it a bit more awkward to safely hang up the caliper, even with the bracket slotted, than it used to be.

The metal tube is a bit more vulnerable to damage.

it can be...

Its not that bad a job easiest thing to do is put line lockers on the rubber brake lines before anything is undone then it just a simple job of bleeding the calipers as you would with any brake system.

I had to do the whole bleeding process about two weeks ago after putting new brake lines on and was fairly easy job with a nanocom... just bleed the modulator via nanocom then did a normal pedal bleed with ignition off. You can power bleed with the nanocom but takes a little longer as only moves a small amount of fluid each time.
