1971 MGB Roadster Brake Problems
Discussion
Looking for some help/advice please.
The braking system on the car is acting strange. When driving the car on suburban roads when you need to use the brakes frequently the feel of the brake pedal changes. It becomes hard with no movement available on the pedal. The car also becomes sluggish as the brakes are actually on. On a motorway the same thing happens but after braking if I do not touch the brake pedal the sluggish performance gradually abates and pedal free play returns. Then when I have to use the brakes again the problem returns, gradually abating until I have to touch the pedal again.
I think that it is a brake servo problem as also if I have to brake hard after hitting the pedal quickly and firmly the pedal actually pushes back at my foot noticeably.
I'm going to have a look at the Servo etc tomorrow. I know that a Brake Servo is not necessary part as early cars did not have them fitted, so if I disconnect the vacuum hose and put a sealing bolt in the manifold take off should the brake pedal behave normally? Or should I blank off the servo vacuum entry pipe too?
Thanks

All the Braking System (Except the Servo) were updated in 2012. New Master Cylinder. Copper/Nickel brake lines, new Calipers, Discs and Pads, new Rear Wheel Cylinders, and of course new Fluid. In fact all of it except the Servo. Should had done that too at the time!
If there is confusion on my Handle (User Name) I changed it this morning to Packman65.
