Power Bleeding ABS Brakes.
I realised that with my Nanocom I think I have the ability to power bleed my brakes. Car is a 2007 Puma

Up to now, I've taken the approach that if I conventionally bleed the brakes every year, and activate the ABS and TC occasionally (say on snow in winter), that will probably be good enough to stop manky fluid building up in the ABS unit.

Should I get with the 21st century and try the power bleeding? Anyone know the process with a Nanocom? Any views or options one way or another? 2007 110 TDCi Station Wagon XS

On my original Nanocom I used to use its 'activate' function on each wheel of my TD5 in turn to keep the ABS free and manually bleed the brakes. The ABS would start sluggish and become noticeably faster which encouraged me to do it twice yearly (not bleeding though). Cheers, Guy.

That's good to know, I may adopt that approach, at least with every service, and forget the power bleeding thing. 2007 110 TDCi Station Wagon XS

You only really need to do it when you're replacing the ABS modulator as it speeds up the process of getting the air out of it.

But if you're just replacing the fluid you don't need to, it's not like some older cars where you had to put the modulator into purge mode in order to bleed the brakes at all.

I bought a pressure brake bleeder a few months ago, amazing bit of kit, well worth the investment as it makes the job of bleeding brakes on anything so much easier.

Yes, I've had Sealey pressure bleeder for a few years, one of the handiest things I be got. Especially useful when you've got no mates, like me Laughing 2007 110 TDCi Station Wagon XS

Bit of thread resurrection here.

Can anyone talk me through step by step how to use a Nanocom to bleed the ABS pump and brakes. I tool my pump out at the weekend to replace to solenoid switches and now it’s back I want to be sure all is good and the air is out.

I plugged the Nanocom in and there is the is the option to Power Bleed, Modulator bleed and then individual test for each wheel. What should I be pressing when? At what point do I open the bleed nipples? I’ve tried them all and I can hear the pump run for a short time, but no fluid comes through. 2007 110 TDCi Station Wagon XS

I found this posted on the Nanocom website, I’ll give it a go and see what happens.

Do a manual bleed first in the order Front Passenger, Front Driver, Rear Passenger, Rear Driver.

You'll then need to do a modulator bleed which is done by pressing the brake pedal as hard as possible to get maximum pressure (this may need a bit of pumping of the pedal to achieve if the manual bleed wasn't too effective). Then select the modulator bleed function. This should be repeated four times.

Once this is done then do a power bleed function on each wheel in turn there'll be a number of pulses over about 10 seconds so select the function, open the caliper bleed nipple and then close it after the pulses have finished.

In my experience the power bleed on the nano com only seems to work on Discovery 2 TD5s.
