So your brake cylinder pressure is 60psi and it won’t go any higher? It’s a bit of an odd question because it’s normally the other way around- brake cylinder pressure is stuck at 60psi and unable to release brakes. This is not a fault. 64psi is the maximum brake cylinder pressure you can get if brake pipe is charged at 90psi (as on freight trains). Once your brake pipe has reduced to 64psi, you’ll notice brake cylinder pressure won’t increase anymore than 64psi even though brake pipe pressure is still decreasing. This is because at 64psi, this is the equilibrium between auxiliary reservoir and brake cylinder. The ratio between the two chambers is 1:2.5 so when brake pipe is 64psi, this is a drop by 26psi (90-64). As the ratio is 1:2.5, 2.5*26= 65psi* is the maximum pressure in the brake cylinder (I.e. a full service brake application). It’s hard to explain without diagrams or animations so I’d recommend trying to find a video on YouTube on this. *I’ve rounded but the true value is between 64-65psi To be honest, you shouldn’t have to use anywhere near 60psi of brake cylinder pressure so I’m not sure why you want more. If you really want brake cylinder to be higher (in other words, you want a higher full service brake application), switch the brakes to passenger mode. The brake pipe will be charged to 110psi and consequently your full service brake application is now 79psi instead of 65psi.
