Hi,

I have an odd question?  I have a kit car which has a brake master cyl, which I think is piped wrong.  There are two horizontal ports with equal sized holes inside the threaded port and a third port with a much smaller hole inside the threaded portion which faces the ground.  The horizontal port nearest the bulk head is piped to the rear brakes.  The second horizontal port is piped to the osf  brake.  The port which faces toward the ground is piped to the nsf brake.  Is this wrong?  My car brakes are perfect, but when pressed, the car pulls to the left, which I think it is due to the smaller hole in the port facing the ground.

Any help would be appreciated

My mistake

It seems odd that smaller piping is used for the osf. Both fronts should have the same sized piping. If the brake is pressed hard the car will brake harder on the front nearside. If the brake is pressed slowly the brakes should close evenly as the pressure has more time to get through the smaller pipe. The faster the brake is pressed the harder it will pull to the left.

Hi kevin,

The piping is the same on all ports, the hole inside the port facing the ground is much smaller, which I thought might be because the nsf wheel is further away and hence, longer pipe. I.e. the large hole port should go to the nsf, and the small hole port should go to the closer osf port?

 

I think you are right. The smaller hole should couple with the shorter pipe. Having it on the longer pipe will make the brakes uneven on the front.

I swapped the pipes and it's much better.  There is still a subtle difference when I brake, I think I'll double check none of the pipes are restricted internally.

Thanks for input
