how to bleeding drum brakes?

when the car is turned on the booster is working there for your brakes are softer then when the car is switched off.

So if you did the bleeding OK and the brakes are responding alright, I would not worry too much.

good luck mate.

Drum Brakes hugh? Is this a car or a truck? Let's go first of all what does the fluid look like in the master cylinder? Is it Black, Brown or clear? Any thing less than clear gets (contaminated with water and dissolving rubber parts in the brake system. if this vehicle has been sitting More than 5 years the plan on going through the whole SYSTEM. the brake systems of the early 60;s and 70's some times used both front and rear self adjusting brakes and the people who worked on them did not understand their principles so the adjuster parts got tossed. Look out for rusted lines and deteriorating rubber brake hoses. if you do find any of the above look for pitting in the master and wheel cylinders when you are ready to reassemble the system go for D.O.T. 5 brake fluid it does not absorb moisture from the air like D.O.T. 3&4 fluids do. Yes the bleeding is the same as the generic car or truck. Flush then R.R.-L.R.-R.F.-L.F. Except Euros and asian vehicles they could be different just remember "longest run first" and don't forget the combination valve (Don't let it pop out when bleeding) if equipped The drums as I recall most of those where just sliders (Just slide on and off) Some DID have a small index locater tab that fit into a hole in the axle flange, and some had a countersink screw or two holding it to the flange. First of all get a spray can of WD40 or ZEP 45 penetrating oil and use it freely. Good Luck Albert D

start from the wheel that,s farther away from the master cylinder first like right rear, left rear, right front the left front. sometimes it takes 2 people. 1 to pump the brakes and 1 to loosen and close the bleeder.

be sure that you are getting a good bleed, farthest tire first then working to the closest to the master cylender. ther is nothing different except location of the bleeder vaulve.

Make sure to adjust the shoes. That will cause a soft pedal.
