[TR] 61 TR3A Question Brakes

I've had mine disabled since around 1975.

The only downside to disabling the valve is that you may notice a low pedal after hard cornering.
At least for me, I've always still been able to get good brakes on the first application, the pedal just goes down farther than it usually does. Kind of disconcerting if you aren't expecting it, but it only takes one pump to bring it back up.

There is a modification to eliminate the low pedal, developed by "uncle jack" Drews IIRC and sold today by TRF (and probably others). Probably a good idea if you're going racing, but not really required on the street, IMO. I forget the change point offhand, but the factory quit fitting the valve at some point, either during TR4 or maybe when the 4A was introduced.
