Kakdu pulls right under braking

[KakaduGuy1]

Hello TOCA people!

Hoping to get a potential diagnosis for why my yota is pulling to the right quite significantly!

My car:

2012 Prado Kakadu KDJ150
200,000km
Wildpeak AT3W - 265/60/18 @ 40 PSI, approx 50% tread left
Remsa HPT pads (recommended by BrakesDirect)
Fremax Carbon Plus rotors (recommended by BrakesDirect)
Fulcrum Suspension 2" lifted shocks and king springs (approx 4 months old)

Symptoms:

Car pulls right under med/hard braking and it needs me to steer left to make the car pull up straight. Locking the brakes up makes the car brake straight.

I have replaced:

Thinking that it may be a stuck caliper and/or glazed pads, I have changed out:

All 4 rotors
All 4 brake pads
Brake fluid
Front caliper pistons/seal kit
 

Yet to inspect:

Rear brake calipers/pistons
Upper/Lower control arm bushings

 

12 MONTH UPDATE

 

So 12 months later and the brake problem still occurring, I ended up taking the car to three different brake places and mechanics only to be told it’s a suspension problem; the suspension places couldn’t work it out either. I ended up experiencing poor braking and lots of shudder and car vibrations under braking before I decided to take her in to a brake specialist.

 

half a day later with concerns it could be the ABS module they recommend a full rotor and pad replacement. Expensive but ok. Car still bloody pulls right! The guys are super keen to find out what’s going on. They cross the lines and work out that there’s definitely something with the brake hoses or callipers.

They did a proper brake force test to identify that the left caliper wasn’t grabbing anywhere near as hard as it should. Rears were fine.
 

$1700 later I have a full new braking system including callipers… I’m dumbfounded how three other places couldn’t work it out.. bloody frustrating!

I have only recently become aware of the need to grease the slider pins on the brake calipers. Rear passenger side wheel was not rotating as freely as compared to the rear driver's side wheel. After looking at a number of YouTube videos on the topic of seized or binding slider pins, the recommendation was to be using an anti-seize grease as a preventative measure. I just happened to have Penrite Copper Eze anti-seize grease. There was also a difference in the thickness of the rear brake pads on one wheel so I ended up swapping them around when I greased the slider pins. 

Just mentioning this as something else to inspect when checking the rear brakes. 

Definitely give the control arm bushings a thorough inspection and look for any cracks in the rubber bushings and movement in the control arms.
