Heat causing caliper rub?

khansmithMember

although this isn't about my Pantera, I thought the great minds here might be able to figure out a more generic brake question on my Cobra replica running GM style calipers and a wilwood dual master cyclinder (no booster) with remote resevoir set up. Here is the issue:
When my car is cool, it rolls with little to no resistance from the brakes. After the car comes up to running temp I notice that the car won't roll after I park it as it did so freely before the drive. The brake lines and the master cylinders reside right above/next to my headers. I have a 428 FE big block so you can imagine the heat. My thought is that the brake fluid is heating up, expanding and pressure increases on the brake piston. What are your thoughts?

Thank You,
Khan
