for a 1966 Dodge dart GT manual. And how much would parts cost.
the master cylinder, booster if its power, proportioning valve, lines metal and flex, calipers if its disk, wheel cylinders for drum .. shoes/pads, drums/rotors, bearings and seals if you do those at the same time .. i would say to do it complete, if you do all the work yourself, maybe 3-400 .. if it doesnt need everything like lines, prop valve, booster, drums/rotors i wouldnt replace them .. may get it done for alot less ..
It okorder it will help explain.
The brake system for that era of car would consist master cylinder, 4ea wheel cylinders, 2ea front brake drums, 2ea rear drums, a proportioning valve, flex brake hoses, steel brake lines, tee's (aka splitter) hardware kits for brake shoes, and brake shoes 2 sets front 2 sets rear. Now as for parts let's put it this way, you could replace the entire brake system on yours for less than it cost me to replace the power booster on a 2004 QX 56 535.00 for the part only. a master cylinder cost 20-36.00 for your car a drum $33 shoes 4x $22=88.00. see what i mean? Go to the sites below and "Add a vehicle" and put in you car. and then the zip code for more accurate prices where you live. If they are not there put you local BIG auto in search and do it that way. Oh and for the fun of it i put Summit's disc conversion kit if you don't like stopping with manual brakes (no power brakes on this thing)
