Re: Next under the hood projects for my 86 4kq
flush the brakes with the brake fluid of your choice, the archives are
full of various methods of making your own pressure bleeder. Just bleed
each one in the correct order til the fluid runs clean. should take
less than a quart. you may want to prepare by dousing the bleeder
screws with penetrating oil for a few days to help get them out without
The manual says Dexron II for the PS - when I got my rebuilt rack I
asked Jorgen, the supplier, what they recomended, they said mineral oil
7.1 (Pentosin). You drain the old and flush it out with the new by
disconnecting the pressure line to the rack and cranking the engine to
run the pump (with coil wire grounded) while refilling the reservoir.
Change the filter in the reservoir while you're at it. May have to
reconnect the pressure line and disconnect the return line from the rack
to the reservoir to finish bleeding out the old fluid. Actually that
might be the best place to flush it out anyway. This could be done with
one liter but you should prolly have two on hand.
remember to catch your fluids and dispose of properly.
brake fluid eats paint, be careful.
there may be a pressure bleeder how to saved on my web site.
In both cases, remove as much fluid as you can from the reservoirs first
with a basting tool so you don;t have to pump it all through the
hope this helps get you started.
