Ok guys, just finished fitting my race spec inlet manifold and been test driving the car but having an issue with the front brakes, running an st202 conversion. Both are dragging badly creating hot wheels and burning brakes. I've checked out both sides and they are sliding on the pins ok but the pistons on both sides seem overly hard to compress. I checked both sides by compressing the piston a little, spinning the wheel which was nice and free, then applying the brakes and trying again. Both sides I struggled to turn the wheels after trying the brakes. Granted the car sat around a little while whilst sorting the inlet but before i remove and strip calipers i was wondering if there's anything else that might cause this given both front are affected. The rears are perfectly fine and release after using brakes or handbrake, only the fronts seem to have a problem. Thanks in advance
