Brakes

I’m sure this has been talked about but with so much info I’m hoping to get the SIMPLE answer lol. My master cylinder is leaking inside by the pedal. The booster is attached to the frame under the drivers seat. I haven’t ever seen something like that.... anyway I want to put a new master cylinder and at sum point expand to disk breaks (keeping it drums for now) in the front. Which master cylinder should I buy?? Truck is automatic and I have no idea how the booster works so one step at a time. Thank you for the help

If your going Disc Brakes either go all the way now with brake upgrade to Dual system or hold off. I would be ditching the single master system and under cab booster ASAP. You will need a disc brake master at some point.

what model truck is it? the 1 tons use a different master than the 1/2 and 3/4 tons. the remote mounted booster system is still widely used today but mostly on medium duty trucks from other countries. The MC on the firewall is the same as those trucks equipped without the booster.
The remote booster works by sensing the pressure when you hit the pedal then boosts the pressure to the wheels. those boosters are still widely supported in rebuilts if it ever goes bad on you. around 200 to 325 depending on the model.
