A few questions
So my truck likes to pull to the right when braking hard on un even terrain. I was told the calipers were bad based on assumption and research. I replaced the rotors pads and got OEM used calipers. Well it still pulls to the right when braking hard. Did I just buy another bad caliper ? Haha. I noticed the inner cv axle boot is torn. I don’t know if that has anything to do with it. I also have another question about the horn and cruise control. I replaced the clockspring thinking that was the culprit. The horn worked for a little bit and than stopped working and blew a fuse. The PO installed reed horns so my guess is a bad ground?? I’m stumped :(

What is the condition of the rubber hose and metal lines?
My tundra pulls under braking even after new calipers etc, I have a known kinked hard line though that was supposed to be replaced but is going to require lots of soaking and time I didn't have at the moment.

2nd vote for brake hose issue. Had the same problem on a 1st gen 4runner.

Bleed brakes
If it brakes OK under light to medium stops yet not on hard stops, I'd suspect some air in the system, try bleeding all lines before anything else.
Luck and enjoy the Runner. :cowboy:

You mentioned nothing about the rear brakes. Uneven braking in the rear can make your rig pull. Jack up the rear end of your rig, pull off the left rear tire and then remove the drum. If a rig pulls to the right and the rear brakes are the cause, it will be a problem with the left rear not grabbing as effectively as the right rear. The reason why I know this is it happened to me. It's how I figured out I had a leaking rear axle seal. My brake shoes were coated and gear oil and not grabbing well.

Worn lower control arm bushings can also cause a pull during braking. Have someone brake hard from about 5 mph while you watch each front tire from outside the vehicle to see if it changes in relation to the body.

No I haven’t had the best weather but was gonna tackle the brake hoses first than check the rear.

Before you do that pull the rear drums and at least make sure they are adjusted properly, often the self adjusting system doesn’t work or will only work on one side and can cause uneven rear breaking. That will also give you a chance to check for evidence of gear oil in the rear brakes like Tim suggested

With this kind of mileage you should absolutely inspect the lower control arm bushings. Depending on the last time they were replaced(dealer probably only does the whole arm to a pretty penny) these things are probably pretty worn. Worth inspecting all load bearing bushings, these are a cheap fix if youre doing your own work.
This assuming all your standard steering components are otherwise in good shape

A few questions
Hey guys. So I rotated the tires and cleaned the rear brakes. No signs of gear oil on the pads I didn’t adjust them because my e brake clicks about 7-8 times didn’t think it was ideal. The drums look fine no gouges. I am braking downhill and I get a severe vibration in the back. Happens at highway speeds when slowing down. It happened before all this btw. Any help would be great!
Thanks have a good weekend!

Also does a front bent sway bar front end link affect anything? I noticed the right front one is bent

Do you get the same vibration slowing down just with the ebrake? It can't be the rear brakes if you don't get the same vibration slowing down.
