Time for new bushings or brake system check?

My stock '86 110 doesn't inspire a "lot of confidence" under an emergency/panic stop.

Whether I'm doing 40mph (on the streets) or 65mph (on the freeway), the truck will unsettle itself during an emergency or short brake stop, and scare the crap out of me. I'm not sure if it's the rubber bushings (could they even do that?), which I can only assume are still the factory originals, or if it's the braking system components.

The truck is at it's stock ride height with factory springs, Rancho RS9000 XL adjustable shocks (currently at their hardest setting, and less than 1 year old), Terra Firma RTC steering damper. Steering is tight with no free play, and other steering components seem to be in fairly good shape.

What should I be looking at?

Does the truck have a tendency of going to one side of the road when you brake? Which you might not realize as you likely overcompensate with steering. But typically when you release the brakes the truck goes the other way. If so, yes, new bushings will fix the problem.
How many miles are the current bushings?

Pretty hard to internet diagnose, but, yes, I would look at all the suspension bushings. They fail over time.

Unless you are meaning that there is uneven braking, which could mean a seized caliper or an oil wet brake or something like that. I assume you know how and have adjusted the brake shoes.

The truck is a RHD ROW vehicle. When I brake suddenly, it tends to throw it's rear end to the right. When I release the brakes it does NOT swing the other way, it will tend to correct itself in a straight line.

I've owned the truck for 2 years now, and don't know how old the bushings are.

Could be either really. Look at all the bushings and see if there are gaps on any of them or if they are loose.

Check all brakes for oil contamination. Ensure shoes are adjusted correctly. Lastly check that all pistons (on calipers and cylinders) are free to move.

John: Quite right, hard to diagnose over the internet, I was just looking for some direction.

What I'm describing could be due to uneven braking, and no, there are no seized calipers, but perhaps it's time to look at adjusting the brake shoes in the rear and the calipers in the front, which I haven't done.

It wouldn't hurt either to replace all the bushings anyway, since I don't know how old they are. I know there are multiple threads out there on what brand and type of bushings to use, but what is the final consensus? Factory bushings or aftermarket? I'll do my homework as to what to what part numbers etc, just need to know whether I should stick with factory or not.

Genuine or OEM rubber bushings. Do not use aftermarket.
