Brake Problem

[LR4 2011]

Brakes Pulling to Left ONLY when Raining. I have replaced guide pins no help, replaced front calibers no help, had front end aligned due to ****** Angle out of spec. Do you have any additional suggestions. It feels like the RT, caliber is sticking slightly or Left engages first.

Try replacing the front brake hoses.
The can delaminate internally, causing a restriction.

Check the brake pads for uneven wear from the old calipers. Or, you could have air in one side of the brake lines from when the new calipers were installed. But these two things would cause pulling rain or shine.

The left caliper could be sticky. You could inspect the pads and see if there is heat checking or more wear on the LHS vs RHS. Realistically rain wouldn't impact that, but temperature might.

I have replaced front and back rubber hoses to calibers so that may not be the issue. New pads rotors front end alignment etc. all done at the same time to eliminate worn parts. I see the soft ware blotched out part of my first comment. The alignment angle between the front and rear seems to be correct.

Has anyone had contamination in the brake lines between the master cylinder and caliper?

I had flushed the brake lines during the replacement, possible the left front could have small amount of air in line?

Brake booster?

I have not traced the brake lines but are they all independent or teed off?
