You might find the front brakes might lock up!!!!!!!!!!!!

BCL would have done a lot of testing of Servos in conjunction with Lockheed for more than 10 years to decide on the original servos of the 410.

Thank you for that, Geoff. I did try that yesterday on dry, straight road. I am pretty sure all 4 locked up. The car stayed pretty much straight throughout but one pair left darker rubber lines than the others and appear to have started further back along the road.

I do not know how to tell if one pair locked before the other. How do you know if front or rears locked first? I am guessing the darker line was the fronts as they carry a lot more weight in a hard stop and that line started further back (about 3 yards before the lighter lines appeared) but does that mean they locked first?

Any advice, please?
