Has anyone ever heard of this?


Read this on another LR site.


"As long as you are not starting with an empty system, you won't need to use a Test Book to activate the ABS.
If you hold the brake pedal down, once while bleeding the rear and once for the front, for a minute with the key on, the ABS will activate and push thru any old fluid."

When we installed my extended brake lines, we bled them the old school way: guy pressing and depressing the brakje pedal while another guy opens and closes the bleed valve on the caliper.

yeah, I think Mike is full of shit. Mine has never done that. Ever.

So you read it too.:p
I asked some questions about how to get this to work?
Does the hood have to be open, bleeder valve opened, etc.?
But was ignored.

I quit giving real advice over there.... I am no match for "The Mike"...
I did talk with him on the phone briefly about the ABS Amigo (why do you think there was a updated version right off the bat? I found a bug in 5 mins of using it.... Storey Was great to talk to and deal with. HE is a smart guy)
mike invited me on a solihul run but we didnt make it the week we were up there. He seems nice and helpful...

Mike says things like that. It makes him look smart. For a while there he was saying if you didn't have your abs faults reset, it would retard the timing of your engine. He never could substatiate it.

Another way to do it, is make up 2 leads with flat spade connectors on each end, connect a switch in the middle, remove the ABS relay and "bridge" the 2 terminals for the switched side of the relay, then flick the switch when you want the pump to run to push as much fluid out as you want / need. If you make the "fly leads" long enough, you can even lay by each wheel and open the nipple / flick the switch all by yourself, no need for any help.

doesn't it have to operate the valves as well though?

I broke down and bought a Bearmach Hawkeye diagnostic tool. I thought about getting and ABS Amigo but the Hawkeye was well worth the coin. It makes bleeding really easy. Especially if you are working on the modualtor or master cylinder. It can do lots of cool stuff and provide plenty of info.

So far I have had good luck with the old fashioned way that Stu talked about. I have done it about 3-4 times on the Rover and once one the wife's Volvo. So far so good on both.

Well, yes and no, depends if you have replaced the modulator or you just want to "refresh / replace" the brake fluid. For just a simple bleed, then you only really need to power the pump to help push the fluid out, this is known as a "power bleed" which is one of the options in the diagnostic tools, the other being the "modulator" bleed which is there if you replace the modulator which will operate the valves to.

The power bleed function makes it a very simple easy task for 1 guy to bleed and change atleast 95% of the brake fluid.

I was always told that using the power bleed was a bad idea. We always did a manual bleed even when replacing the pump/valveblock.

Wiil T and I replaced the modulator on my truck and we bled it the old fashion way. I'm sure bleeding it with testbook speeds things up and makes it easier, but apparently it's not neccessary.

Wasn't there something on here about putting the truck through paces to activate the ABS/TC/HDC so it worked the vavles to bleed the valves in the modulator? :rolleyes:

Just confirming, this Bearmach is not only a diagnostic tool it somehow operates the valves on the modulator for a brake bleed?

If so it is worth it for that alone.

$650 to bleed your brakes? No it's not.
