Intermittent strong pull to the left during hard braking

Hi all,

I'll apologize in advance for the lengthy post.

I've been having a strong pull to the left when braking for a couple years. Since then the rig has had a ton of work done. A lot of what was done was to try and eliminate the issue but it's still pulling, albeit not as strong and less frequent but it still happens and scares me because when it pulls I have to correct at the wheel and when I correct and then the steering snaps back the truck wants to go right cause thats where the wheel is pointed.

The massive mistake I made was lifting the truck and having a bunch of work put in before the braking/pulling issue got resolved. Not sure where to go from here, I've gone to a couple different mechanics and after a bunch of work they say "when you lift a truck sometimes issues like this come up and you just have to live with it."

The trucks been through a lot but long story short is, the truck was totaled in 2016 and I ran out of cash so I sold it to a friend, a year later he sold it back. When I got it back it had this issue along with a horrible steering problem.

This is the work that was done before the pulling issue, but the truck was in possession of a friend:

Front brake hoses
Bilstein 5100s
Moog Upper and lower control arm bushings
ball joints

This is the work that's been done since the pulling was an issue, trying to get it in order:
1st Mechanic
Steering column yolk
Extend rear brake lines
Toytec 3" springs
Lower diff
Pan hard bar drop
2nd gen tie rods
Tundra brake upgrade, rotors, pads, calipers
SRS F5s and tires 285/75/R16 Yokohama Geolanders
Rear brake cylinder, and shoes
Rack and pinion
Power steering pump - Pump ran dry about 15 miles after rack job

2nd Mechanic

LCA bushings (again)
ABS actuator unit :sobbing: - didn't fix anything
Brake pads (again) - made a world of difference

--

Troubleshooting done. Steel braided lines swapped from side to side, calipers swapped, ABS replaced
--

After the pads were replaced for the second time, the pull became way less frequent, almost non-existent. However, now I took it on my second road trip since all the work was done and I had to emergency stop on the freeway and it pulled, scaring the crap out of me. Afraid to take it back to a shop and expect a different response. I'm not very mechanically inclined but these are the possible causes I can think of. Hard steel line kinked or bent (but if this were the case I don't the issue would be intermittent), possible frame damage (but it didn't do this after it was totaled), maybe the M/Ts are biting when the weight shifts forward causing it to go with the camber of the road (but it has pulled before when going straight).

Has anyone seen this issue before or maybe has an idea of what could be causing this? Any help is appreciated.

following...my '97 with SS lift has started front end shaking at highway speeds and when braking feels like the wheels are loose pulling side to side. replaced rotors and pads but not calipers.
 
Maybe one or more of the pistons on your front brake calipers are frozen causing one corner of the car to "brake harder". That caused the steering to pull on my 4R under hard braking. Though, one would think that a mechanic would notice this when replacing the brake pads if that was the issue.....
 
If you’re not replacing those LCA bushings with OEM or poly that could very well be the issue. All the others seem to be total S*** from what I’ve heard.

Also, make sure the rear brakes are adjusted correctly and all 4 corners are properly bled.

Does your steering rack have play?
 
If the LCA itself is bent in the slightest, that may be the problem. I saw such on a truck once.

How does the tread look on the tires?

I haven't got the side to side pulls when braking, it's always to the left. Did replacing the rotors and pads fix the issue?

I think this has been ruled out by now but we were thinking the same thing before the caliper replacements and even after they were replaced, I had a mechanic swap them thinking we'd see the pull going right.

They were originally replaced with Moog and yeah they were crap, failed within a year. Got OEM installed now.
 
Jack up the front of you vehicle so that both front tires can spin. Give each a spin. If there is resistance, more than likely on the side you are pulling towards, I would say check your caliper. Mine was pulling driver, so I replaced the Napa TBU caliper on the driver's side. I decided to throw some new pads on the next weekend and noticed the passenger side was also frozen and not letting me mount the new pads. So over two weeks I replaced both front calipers and pads and bled the brakes. Now they feel FANTASTIC and don't pull.

I took a look at the LCAs and I couldn't see a bend but I'm not sure a good way to look. Any advise on the best way to measure for a bend would be?

Tread looks the same, no unusual wear.
 
This might not be it but almost every car I dealt with that had some weird random pull was the proportioning valve sticking...I know the 2nd gen used a level sensor for the rear for rolling but the 3rds don't afaik...I would brake flush a few gallons through the system and sometimes it would work ok...sometimes replace was the only thing that worked.
