i keep bleeding them.i keep pumping the brakes and two wheels wont hardly leak any oil out when i crack them. i tried pumping oil from bleeder up to top but it wont take oil.my booster is good and so is my cylinder.how can i tell if my calipers are bad.also the wheel that wont bleed, the brakes on that wheel were not wore out.
it,s not oil, it,s brake fluid. start with the right rear wheel then the left wheel, go to the right front then the left front. have someone pump the brake and hold it while you loosen the bleeder. then the brake will go to the floor and tell them to hold it while you tighten the bleeder. keep paying attention to the master cylinder because you don,t want it to go dry.
If you have drum brakes on the rear adjust them up before bleeding the brakes this way you will get pressure built up in the system by having the brake shoes closer to the drums to help force the brake fluid out the bleeder valves when opened.This step will only happen if you have drum brakes on the rear but if you have disc brakes all the way around you should be able to get pressure built up in the system at any time unless you have a master cylinder going bad on you and not holding pressure.It would of been nice to know what year,make,model,engine size you have to help with your question but most people that put questions on here never leave this type of information because they think people who answer these question can see through the screen to see there car.
A precipitate can be a result of a reaction. It is not added in but is a by-product. At least that is how I typically use the terminology. It can also mean that it is a substance that has fallen out of the solution. A suspension is the result of two or more chemicals added together that do not readily mix and form layers.
