Hydroboost/Powermaster brake lines

[UNGN]

The brake line fittings in the master cylinder appear to be reversed between the Powermaster and the Hydroboost.

Does everyone just switch the rear line to the front and the front to the rear, or change the fittings?

I just reversed the two. Plenty of slack in the lines to make it work.

This might be a stupid question.... but if the master cylinder is a straight bore size... for both the front and rear..... does it really matter?

I could see on one that had the big bore on the rear.... and the small bore on the front....

Hydroboost conversion

On the Powermaster, the rear port goes to the front brakes, On the master that we use, the front brakes go to the front reservoir. In all cases the larger reservoir feeds the front brakes. GM made the lines so that the 1/2" size goes to the front brakes
