1972 270 Brake Problems
Posted: Wed Sep 13, 2017 6:35 pm
Hi Friends,\nI'm having difficulties with my brakes at this point. I have a 1972 270 travco with the 413 engine. I'm a bit confused on the nomenclature for the vehicles. My manual says it should be a M375 but my van has the dual power brake booster setup that is of the M300 vans. Can anyone clarify?\nI bought the beauty (it really is quite lovely 
) last year and the brakes were spongy back then. I've been tackling many systems but I haven't learned much about the brakes yet. I take it out regularly and they have been operating consistently until this past weekend. I took it out and it had next to no brakes to my chagrin. I pumped the brakes repeatedly and after 3-4 pumps the brakes started to work, but not nearly enough to navigate traffic or intersections.\nI located the master brake reservoir above the front drivers wheel. Is this the only place to add fluid? I didn't see a way to gauge how full to have the fluid. I pumped in some new fluid but it appears it had enough fluid in the reservoir. The manual suggests checking the brake booster units (i have two-front/back) next then the wheel brake assemblies. Does anyone have any leads on what this situation sounds like? it looks like the solid metal tubes that connect everything are in good shape. I don't have the setup to be removing wheels and working on the brakes, but may have to acquire such means. Are the brake power booster readily inspect-able? I don't under how the vacuum function works or how to disable it to check for proper functioning...\n\nAny help / wisdom is appreciated. I suspect I'll need to save my money for parts and do as much labor as I can. Can the wheel hoses be replaced without removing the wheels, for example?\n\nMuch Appreciation for your Thoughts!
