Tip & How-To about Yugo Hatchback
There are two basic methods of Brake fluid bleeding.
By only one person,using a Vacuum Pump/Brake Bleed Kit.
By two persons,using the pressure of piston at the master cylinder.
Lift up your car with 4 jack stands, and remove all wheels.
In two cases, the most important task is to make sure the bleed nipple can be loosened.
You need a box wrench that fits the bleeder nipple. A little penetrating oil on the nipples overnight will help. If it doesn’t help, apply heat (butane torch or similar) and then spray again with WD40. With some moderate tapping with a hammer to break any corrosion, loosen the nipples.
If the bleed nipples are welded solid in the caliper then you need to have the nipples drilled out and heli-coils fitted by a local engineering workshop.
So it is a good idea each time you bleed the brakes replace the bleed nipples with the new one.
Use at least, High-Performance DOT 3 or DOT4 Brake Fluid.
An unopened can has a long shelf life. An opened can absorbs humidity, and should be discarded within a few weeks.
Fit a piece of clear tubing over the bleed screw nipple and run the hose into a clear bottle. Unscrew the Bleed Nipple about a 1/4 turn and go pump the brake pedal and keep refilling the reservoir before it goes below the 3/4 mark or air will be drawn into the system, close the bleeder.
Torque the bleed nipples to only 30-50 inch pounds (about 3– 5`foot pounds). Don’t forget to put on the rubber caps.
Repeat until clean/clear fluid comes out. Move to the next wheel until all are done.
Depend on what dual braking system your car has, the pattern is different.
Ensure you have a nice firm brake pedal before you take the car off the jacks.
Make sure that you clean up any spills with a rag and ensure that you dispose of your waste brake fluid in a responsible and safe manner.
