How do I bleed the brakes on a 84 cadillac deville?

I replaced the master brake cylinder and already bench bled it but I don't know how to bleed the lines themselfes. I can't find the screw or whatever to bleed them all I think I know is it's somewhere around the front disk brakes.How do I bleed the brakes on a 84 cadillac deville?See here

You will need to start with the right rear, left rear, right front, then left front. the rear wheels you will need to bleed while the car tires are either on the ground or on ramps. This car has a brake proportioning valve in the rear that is height sensitive so it will not let fluid to the rear wheels if it senses that the rear suspension has extended itself. Good luckHow do I bleed the brakes on a 84 cadillac deville?on the front they are on the calipers, towards the inside of the wheall well it might have a little cap, and for the back, they will screw into the wheel cylinders, just follow the rear brake line and when you come onto the wheel cylinder it should be above it. they are kind of tiny, make sure you have brake fluid, then just pump the brakes a few times and hold down then have someone open the screw and let some air out, make sure you close it back up,reapeat for each wheel, you might have to reapeat it a few times. gd lk.How do I bleed the brakes on a 84 cadillac deville?Bleeder screws look alot like grease nipples and on drums are located behind the drum backing plate. On disc they will be on the brake caliper. Always start with the right-rear, then left-rear, then right-front and last left-front. Remember to get a friend to pump the pedal firm (but not to the floor) and you just crack the bleeder open for like a second then close it. It may take longer but it eliminates any chance of drawing air back into the lines. Being that the car is an 84 you might want to replace all the brake line while it's down; its quite simple to do and a bit more piece of mind.How do I bleed the brakes on a 84 cadillac deville?If you jack it up and remove tire ,(front wheels), you will see the %26quot;bleeder%26quot; on top of the caliper %26quot;body' it is at the highest point, (so the air will congregate there! It should have a little plastic cap over it to keep the dirt and stuff out (but they quite often are missing).... I generally toally remove the bleeder, and check to see that it is open so fluid can run out! If plugged, you can clean it out with a small drill bit, or wire brush bristles, or whatever you can get to work! Quite often %26quot;it may help you_,-- fluid may drip out slowly, - if it does it is bleeding itself for you! Let it drip till you see no more bubbles coming up out of bleeder, and then tighten down %26quot;moderatly tight%26quot; This is a small hollow screw and can be twisted off if too much %26quot;torque applied!



Rear brakes work similar, but I think you still have %26quot;drum brakes%26quot; on rear, - the bleeders are located on inside of %26quot;dust covers%26quot; near top, -- located just above where the brake line goes into wheel cylinder! They work exactly the same way as the front ones do! best sequence is to bleed right rear (pass side), then left rear, --right front, then left front! This bleeds the longest line first, and then the shorter one on each end of car! Each time you shut off bleeder, -- check to see that reservoir is still full, (you don't want to put air right back in again)! You can catch fluid in small container! If you have a small piece of tubing that is right size, (it is nice), as it can be used to make sure fluid makes it to container instad of all over everything else! of course this is not manditory! I have a piece of clear plastic tubing from an old washing machine, - that I use, as I can see air bubbles travel through line (if it drips by itself),-- this way I can tell when only fluid is flowing.--It also helps to keep dirt and stuff out of fluid!



If it does not %26quot;run by itself%26quot;, you need a little help! Another person would be nice, - but if none available, - you can make a %26quot;dead man%26quot;, - by finding a board or something the right length to go between seat and brake pedal! Start engine, pump brake up, - insert %26quot;block%26quot;between seat and pedal, (put towel coat or something over end that hits seat so that it doesn't hurt upholstry! -- Now you can just barely %26quot;crack%26quot; bleeder loose, and if you have your finger on top of bleeder hole, you can feel bubbles flow out! --- When bubbles stop, flow will feel%26quot;smooth%26quot; as fluid runs out! Check reservoir, pump up pedal again and bleed each one in same manner!



Now you may not have to go through all this -- if you try this trick! ***** Start out by using your %26quot;deadman%26quot; on pumped up brake, -- %26quot;crack loose%26quot; brake line at master cylinder, (just barely loosen)- when it is loose enough, - it will let fluid (and hopefully air) out right there! Do it a couple times on each line, - sometimes this will push it %26quot;up tight%26quot; enough that when it bleeds out where the fitting is loose, the trapped air will flow back out that way. This depends on how much air entered the brake lines while master cyl. was off, -- and wheter it already has pushed air down further into lines when master cylinder was going bad!



When at least most of air is out of lines, the pedal should %26quot;come up%26quot; pretty good when you push it down, and if you pump it,- it generally doesn't raise much over an inch or so when you stop and hold it steady! After letting it off and waiting 4-5 seconds, - it should not go down real close to floor when you jam it down with out pumping! Of course all pumping and bleeding is done with engine running!-- Since this is %26quot;power brakes%26quot;............... Without engine running, pedal will be hard as a rock sometimes!



Now carefully test drive car, -- if brakes work right you are done, -- if not,- bleed some more from wheel cylinders!





Note Brake fluid is soluable with water, so a little dish soap and a water hose will wash it off siedwalk or driveway quite easily!
