Make sure the master cylinder is full and that the vacuum line going to it is is secure wit no air leaks. If as you state the brakes not being applied only at the drivers front and passengers rear wheels, but the other two wheels are working fine you will either have a leaking/blocked master cylinder, leaking/blocked brake lines feeding each of those wheels, or a bad proportioning valve. To trouble shoot raise the bad wheel and crack open the bleeder valve, have an assistant apply the brakes if a nice clean steady stream of fluid comes out, MC is OK, and valve is OK, any bubbles of poor flow indicates leak in system. Very little flow bad MC or blocked lines/valve, etc.Do the same for the rear wheel and you should be able to determine the fault.
Does the car have ABS ? And does it have an equalizer block for the 4 wheels ? It sounds like the ABS has been affected, or there is an equalizer block that is stuck on the front wheels only. Can you open the bleeder or the rear line on the master cyl and get fluid to come out by depressing the pedal ?
Hi Chris, The brake system is basically very simple. If you have duel braking on your vehicle, the usual method is having two brakes operate on the front with for example the left rear and the other system will also operate two front and the right rear. This type of system will have two calipers on each of the front wheels. The tandem system works in a slightly different way, having the forward part of the cylinder pressurizing the rear brakes and the rear part of the cylinder pressurizing the front. I think under the circumstances you are describing, I would have a friend sit inside and pump the brakes repeatedly until the system becomes pressurized (maybe twenty thirty times of pumping the brake pedal) and then ask him or her to keep it pushed firmly down until you find out where its leaking. The amount of brake fluid you report having been sed would indecate a severe leakage. Check the lower parts of the rear wheels for signs of leaking wheel cylinders and then dito for the front wheels. Any signs of wetness at these areas and along the brake system (the plumbing or pipe work) will indicate where the leakage is. If you cannot identify a wheel which is leaking, carefully inspect around and blow the master cylinder and if this no sign go along the fluid lines, taking special note of where the damaged pipe was repaired. If there is a blockage in the line, air may be trapped at that point causing difficulty in pressurizing. Once the place of leakage has been identified it must be attended to before bleeding the system. When bleeding, begin with the wheel furthest from the master cylinder, and work your way back to the master cylinder one wheel at a time, until you reach the closest.Keep in mind that you may find it required to pump the pedal many many times before opening the bleed nipple.Regards John
Try and pinpoint where it is leaking.First start by cleaning everything off (brake fluid) of wheel hub.Check to make sure the bleeder valve is closed(tight).While you have someone applying pressure to brake pedal look on back of wheel hub and search for leak.Search on brake line,brake line fittings,around bleeder.
Those are fuel lines and they may have just rusted out one is the main feed thats the largest the next largest is the return line and the smallest it a vapor recovery line that could leak fuel when the tank is full or up or down hill condutions YOU NEED TO CHECK THIS OUT
you mean from "near" your rear passenger tire. Tires don't have brake fluid in them...!
Take a look at the inner part where the wheel mounts to the axle. There is a brake line there, so look to see if it looks like the brake fluid is coming from it, (and that you verify the brake fluid resevoir under the hood is low) or that it might be from the brake drum area. If it's from the brake drum, you probably have a "wheel cylinder" leaking, and need to remove the wheel and drum to verify this.
You can take the line off and take to a parts store that sells metal brake pipes by the foot,there is different size pipes as well as flared end nuts.You will have to bend the pipe to fit then bleed the brake system.Iwould suggest to take it to a shop and have a pipe made up.
