ford scorpio brakes

Hi all,I have an old Scorpio that needs brake bleeding, is there a set sequence to follow or can i use a pressure/vacuum/one man bleeder unit,? is there a bleed nipple on the abs pump ,just like to know these things before i spend all day wasting my time !.

With any luck you've not got any air into the ABS valve block. It can take thousands of man-hours to get out again.

You really need two people. One at the caliper and one on the brake and keeping an eye on the header. Whatever you do, do NOT let the header run dry for reasons above.

First thing to do is to dispel all the pressure in the lines. Do this by pumping the pedal with the ignition off until it goes completely solid. If you try and open a bleed nipple whilst there's still pressure, you'll end up in A&E

Get a jam jar with a little fresh fluid in and run a pipe from the bleed nipple on one of the rear calipers to the jar with the end under the fluid.

Have someone lightly rest their foot on the pedal, open the bleed nipple and then get them to switch the ignition on. Let the fluid run until you see fresh stuff with no air coming down the pipe then close the nipple. If it takes more than a minute, close the nipple and switch the ignition off for a bit to avoid stress on the pump.

You then need to do the same for the other side. It won't take anywhere near as long since (IIRC) the Scorpio is split front and rear so you're just flushing one side.

Front brakes are bled as normal, by pumping whilst opening the valve, closing it and then letting the pedal return.

or use a pressure kit and start at the shortest run, ie front closest to the res.

the abs will be fine unless u have fitted a new one.

You'd only pressure bleed the front. The pump does it for you on the rear circuit.

Thanks for all your advice,I did'nt realize the rear brakes could be bled by the abs pump, will try in morning and let you know !!!!

That is provided they did stick with the electric pump job (you can hear it whirr away when you put it in ignition) on all of them. I've only done the earlier ones.
