Help needed!!While running on highway, brake warning light keeps blinking on and off, temp guage climbs to above 200F (between 200 and 250F) checked master cylinder, plenty of brake fluid, no leaks, took off wheel, no drags, slight pull to left front wheel, checked wiring to master cylinder, etc. no results. When car is standing still and idling, temp drops back to 200F. Gets hoter when running! viscous fan seems OK, any suggestions appreciated. regards to all, Abe G
