Some of it could be the lining material and composition. My Burb does that especially when it's cold.
When you replaced the pads and calipers, did you clean and lubricate the mounting surfaces and the pins/bolts? With high temperature brake lubricant? Many people forget these important steps.

Is it grabbing in one direction or the other? Or are the brakes just "grabby" when cold?

How are you Rubber Hoses? When colder temps they can tend to contract. as the system heats the line will sometimes open and flow better. Just food for thought. :33:

Just because, check your rear shoes for adjustment.

All the previous suggestions are correct. If the brakes are otherwise decent after the initial few stops, suspect pads. Have seen that happen with rear drum brakes locking up cold especially in damp conditions. Try a different, preferably name brand pad.

For diagnostic confirmation make sure the rear brakes are working by carefully road testing [low speed] on a dirt road with panic stop or using a heat gun on rear drums after several hard stops.

Thanks All Rear brakes have no adjustment hole, Should defenatly check those and replace shoes how would i know if i should change the drums?
Front brake Hoses New. Was good before in cold temps?

I'd say it's just composition of the materials/weather I believe my burban does it every now and then too with the right conditions, definitely felt one the other week but that was because of the ice on the road. Just be mindful the first couple miles and don't worry about it?

:imo:

Wife's 22 Honda will almost rust over the entire rotor surfaces overnight sometimes in the right conditions. Just surface rust but I mean damn lol.

Only other thing would sticky calipers, but you don't really have those symptoms.

Drums need to be measured to know if they can be cut or not. I also always recommend to cut out a slot to the star adjuster on the backing plates so they can be adjusted without pulling the frickin drum off.
