My car is an early car with Dunlop brakes and instead of the proper Lockheed servo, it came to me with a "PowerTune" knockoff version of a Lockheed servo. This was discussed in this thread when I purchased my car. The brake feel is still quite notchy, almost as if the piston sticks in the cylinder, then releases suddenly,, making it hard to smoothly modulate the brakes. It's really noticable when I switch from the Rover to my Daimler V8-250, which has nice, smooth brakes after a servo rebuild.
Given the horrible reviews I have seen of the PowerTune units, along with the fact that the unit had to be rotated to mount properly, I have decided to replace it with a proper Lockheed. My initial thought was to source a used unit and send it to Power Brake Exchange, as they have rebuilt other servos for me. However, this morning I received an e-mail from SNG Barratt with a link to this video for what is supposed to be a new Lockheed servo. At $175, it's cheaper than a rebuild, and it does look to be a decent quality part.
I'm curious if anyone can say if this unit has the proper assist ratio, as I am worried that extra boost will make the brakes feel a bit numb, or perhaps too touchy.
Thoughts?
