1989 toyota pickup pull hard right when braking
My truck started pulling hard to the right when I hit the brakes. It drives straight as an arrow when driving, but then as soon as I tap the brakes it wants to put me in a ditch. Does anyone have any idea on what could be going on? Thanks in advance.

It has always been the opposite caliper not squeezing hard enough or a lot of play in the suspension/steering on one side.
Grayghst, check your brakes all the way around to make sure you have plenty of friction material left on the pads and shoes then jack up the front end and make sure you don't have one brake dragging, do the same for the rear just to be sure.
then apply the brake (have a helper do it) while you try to spin the tires by hand. I'll bet that the right side brake applies with just a little brake pedal pressure and the left side may not apply at all. (note: this applies to the rear brakes as well but will not usually cause much of a pull)
This will prove that the left brake caliper is seized or the line to it is plugged off, hard line mashed flat or kinked, hose twisted or internally collapsed etc.

I agree Akwheeler. Unfortunately I don't have that much experience with braking systems, just trying to help the community the best I can. Good luck with your truck Grayghst.

Alright so I spun the tires. The left side seems to have more movement when the brakes are applied than the right. My right side shock is blown also. So you're saying check brake lines.

if you get a good solid stream of fluid out of it when you first open it that is another indication that the one or more of the caliper pistons or one of the brake pads is not moving like it should.
for the cost of a new brake caliper and the pain involved in rebuilding one on my own I prefer to just buy new or reman calipers. I also prefer to replace brakes in pairs, less likely to get a pull that way.
So, after the test I described above, my best recommendation is to reface or replace both rotors, replace both calipers and front pads.
If you don't get any fluid coming out when you bleed that caliper (or very little) you need to find the blockage in the line, either in the tubing or the hose.
I should mention, if your bleed screw doesn't have the rubber cap on it anymore it may be packed full of dirt and restrict the bleeding and give you a false result on the test above.
You can clean out the bleeders by removing them completely and running a small drill bit down inside and through the port on the side at the bottom (don't drill all the way through anything, just enough to clean out the passage).

When I cracked the valve on the left side the pedal didnt go in at all and didnt shoot out. But the right side shot out and the pedal went in

If you did that means that no pressure is getting to the caliper, you can move up to where the hard line and hose meet at the top of the hose and crack the fitting there when the pedal is pressed to see if you are getting pressure that far.
If you do then break the connection at the bottom end of the hose, if you get pressure there the hose is good (unless it's cracked or bulging).
If you get pressure at the bottom end of the hose crack the fitting at the caliper, if you get pressure there your problem HAS to be the caliper.

Grayghst,
Please keep us posted and don't be intimidated; Aside from lug-nut wrench, I only needed a screwdriver and long-nose pliers to do my brake pads.

Where is your truck from? I know the deicer they put on the roads here is hell on calipers, I drove for fifteen years without ever having a caliper problem and have replaced five in the last seven years since they started using deicer heavily. Including one a Ford and one on a Dodge so it isn't a Toyota issue.

I have a 93 x cab v6 that has pulled right on me for 10 years or more. (I bought the truck brand new) I've litterly only put 1 set of pads on this thing in 26 years lol. Im horrible at maintance but going to rebuild the breaks now with other things which is why I found this sight. .

It's been my experience that pulling brakes is caused by the caliper not functioning properly... making it "pull" in the opposite direction of the sticking caliper...
Either get a kit and fix the old one or get a rebuilt one and replace...

Just got back from a break shop. They want $900 to replace rotors, breaks and calipers and re pack 4x4. Said calipers were shot which after 26 years in sure LOL. Not sure about that price though.

It wasn't that bad of a job and I am not very experienced. My dad helped me and I have the service manual. Honestly the hardest part was bleeding the brakes. But I got out of there for about $500 with new rotors, calipers, pads, used brake booster and used master cylinder.

Sounds high to me, Les Schwab quoted $500 on my mother in laws Subaru and I told I would do it for her. Turns out all she needed was pads, they just refused to do brakes without replacing calipers and rotors. I've done calipers and rotors on a few rigs, it is more of a job on these older Toyotas because of rotor being captured, but still not rocket science. I bought a big socket (55mm I think?) to do the axle nut on mine last time, but you can do it with a punch or even a set of channel locks. Just make sure you get the wheel bearings packed good and don't tighten them too tight. You don't want any slop, but if in doubt remember that too loose is better than too tight.

If I were you, I'd do it myself anyhow. All you really need is some wrenches + a pull scale (the ones for baggage are just fine) and a tourque wrench. I suggest buy one of the 55mm sockets. https://www.yotatech.com/forums/f115...socket-199385/
