Hi everyone
I've got a 90 troop with the 4ZE1. This weekend I plan on bleeding all my hydraulic systems to replace the fluid (brakes, clutch, and power steering). I haven't done this before, but reading through the Hayne's manual everything looks easy enough. However, I've worked on my truck enough to know that just because it "looks easy in the manual" doesn't always mean it is. Is there anything I need to look out for/be careful of when doing these jobs, or is it pretty straight-forward? I know people change brake fluid, but am I wasting my time with power steering and clutch? I don't hear of people changing these fluids very often. Mine haven't been changed (other than topped up) for 5 or 6 years. Any and all input is much appreciated. THANKS in advance- <img src="/forums/images/graemlins/cheers.gif" alt="" />

be careful not to bust the bleeder fitting on the caliper when you are tightening it back on. ask me how I know <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />

Bleeding the clutch hydraulic system is often overlooked and you will see the benefit when the old fluid that comes out is dirty and black.

The biggest help you can get for these procedures is to get a friend to help you. they hold the pedals down while you crack the bleeders.

You can bleed the brakes and hudraulic system alone by using a piece of pipe to hold the pedals down, but that is a p.i.t.a.

I am assuming you are not using any one-man bleeder kits, i have not tried any but i'm sure it would make the job easier.

Also- be careful of siezed bleeder valves, sometimes you can break them off in the caliper if you rally on them too hard trying to open them. Also, make sure you use a 6-pointed wrench or socket to prevent rounding them off. Versus 12 pointed.

Cheap one man bleeding system:

Take a schrader valve stem cut one off of a tire or a bike tube. Put it in-line with your bleeder screw. Put some tubing over it and use some small hose clamps to keep it airtight. One man bleeder system.

I still prefer the friend system so I can watch and see what's comming out (air/dirty fluid).

Thanks for the advice guys. Bigpoppa, if my friend doesn't show up I'll give the schraeder technique a try - I like to mountain bike so I've got plenty lying around. Anyone else?
