Hello, i just starting having some brake issues with my rig the other day. thankfully it was noticed while going pretty slow and on our farm. Basically whats happening when i hit brakes is it starts to slow down then pressure drops out and when pressure drops my booster vent is making noise and my engine idle changes. But this only happens intermittently. I just bled brake system this morning and took for drive definatly working better but still loosing pressure after about 5 braking events in row(intermittently). And if i pump brakes when stopping after the 2nd or 3rd pump i can make this prssure drop happen it seems...... i do not have any brake fluid leaks and have res topped off after bleeding. Any input would be great...
thanks mike
