on my 89 4runner...Stopped at a light the pedal slowly fades..I know its the master cylinder, but iv'e never done one before....Are they easy?
I don't and am getting ready to swap my 13/16 bore for a 1" in my 4wd... So please enlighten us Nuff!
thanks..Im thinking friday i may get involved in that..I may just bleed the brakes first thou to see..Also, kind of a stupid question, but where is the master cylinder plunger? also im having a brain fart right now, but can you bleed the rear drum brakes?
that is correct sir the only bit that might be a bit different is most master cylinders come with plugs in the fittings that can be used for the bench bleeding process. bleeding your brakes: start farthest away from the master cylinder and work your way to the closest. meaning; rear passenger side, rear driver side, front passenger side, front driver side. and its also a good idea after you have bled all 4 corners to go and bleed all the T fittings or connections in the brake system if you have let any of the lines run dry. use the same method as above, farthest to closest; T fitting on axl, rear proportioning valve, distribution block (usally on the firewall), passenger side hose to line connection, driver side hose to line connection. i cant say how much i recomend that you go and buy some 1/4in clear rubber tube and a set of flare wrenches in sizes 8,10,12,15mm. you DO NOT want to strip any of the nuts,valves or fittings. investing now will help a crapload later, plus you can loan your tools to friends for beer to help pay off the investment. online haynes manual method of changing a master cylinder: http://www.autozone.com/az/cds/en_us/0900823d/80/19/01/75/0900823d80190175/repairInfoPages.htm bleeding procedure http://www.autozone.com/az/cds/en_us/0900823d/80/18/a3/b1/0900823d8018a3b1/repairInfoPages.htm good luck
