So i installed my rear 5-lug swap a few days ago, could only do the rear because i do not have the axles for the front right now. I switched out the control arms, the hub, rotor and caliper. Now when i drive and the car has load to the back and more towards the right side, the eBrake light comes on, and will turn off then the vehicles levels out again.
My first approach to fix the problem was to check all the brake lines leading to the rear brakes. i made sure there were no leaks or snags, and i made sure that the eBrake cable itself was installed properly. Everything looked ok.
Next thing i checked wuz my fluid level. it was a lil low from when i bled out the new brakes, so i filled it up and took it for a spin. The problem was not fixxed.
Soooo.... i think it could be unequal pressure in my master cylinder pistons. So tomorrow im going to rebleed the entire system and see if maybe this will fix the problem.

If anyone has had this problem before and knows the solution please let me know. will be helpful
