Power brake booster

I have a 1976 cj5, wondering if I can get better braking with a booster or just get a new master cylinder? My brakes feel spongy. I've bled them to death!

a booster will not fix squishy brakes. I'd start with all the "soft" portions of brake line, then replace the master, and finally the wheel cylinders if nothing else fixes it. start on the cheapest and work your way up In reality, it's likely a little bit of everything at that age.

Your old rubber break lines are worn out, get new ones or upgrade to stainless lines. Replace them and re-bleed yet again.

I don't think so. You can get a smooth brake from a power brake booster no doubt about it but it will not solve your "spongy feel" brake.

This is the best route to go.

Is a power booster even needed for most users?
