71 K5 Brake Upgrades (LMC Hydraulic or larger Vacuum system)
I recently bought a 71 K5 Blazer. It's amazing. Even with discs in the front this does does not want to stop. Brakes are in good condition, rotors recently turned.
Anyway. I'm a newbie so I'm needing some help deciding on upgrades. My mechanic is recommending a changeover on the rear from rotor to disc. He also recommended upgrading the vacuum system to a larger system. Something about using a 1 ton system rather than the original 1/2 ton system. This led me to find this LMC hydraulic kit. Hydraulic Brake Assist Kit | 1967-72 Chevy & GMC Truck 1969-72 Chevy Blazer & GMC Jimmy 1967-72 Chevy & GMC Suburban | LMC Truck' Can anyone help me here? I do a lot of city driving and this is my daily driver. Here in Nashville there's lots of short stopping as we apparently have outlawed the usage of turn signals. |
Is this what you are looking to do with the 1 ton booster swap?

That's a great guide. A buddy was telling me that if I went with the hydraulic system that it potentially feeds off the power steering pump and that if the power steering goes out, so does the brakes. Not sure if this is true to be honest.
Many trucks especially diesels still use hydraulic brake boosters. If you lost brakes completely when the engine shut off manufactures would not put them on vehicles. |

This is accurate to a point. With hydraulic brakes if you loose power steering you loose "Power" brakes. The brakes will still work but the pedal will just be a lot harder to press down. Same concept as if you loose power steering. you can still steer but its a lot harder to turn the wheel.
