Hyundai 59110-3Q300 Booster Assembly-Vacuum

In order to maintain vehicles in good condition, regular checking of brakes is necessary. When it is required and as per the specifications, these should checked upon removing the wheels or when there is a doubt about any defect. One side pulling of vehicle under application of brake pedal, noise squealing during applying the brake system, too much travel on the brake pedal, pulsation of pedal or leakage of fluid when pressing the brakes are signs that your vehicle might have problems with its braking system which may be easily diagnosed by mechanic who will immediately advise you on what to do next in order to rectify it. The wheel lug nuts have to be loosened and removed; then the car has to be lifted safely using jackstands; finally, you need to take off all wheels while inspecting them for damage as well as wear marks. For each caliper, disc in this case comprises two pads: an outer pad and an inner one whose thickness's must be verified through looking at inspection window on either side. More examination requires removing calipers so that pads can be cleaned properly if needed. Micrometer is used for measuring disc thickness while gouging resulting from burning instances or scoring are indicators as well. It's also very important that after having taken away the wheels examine each brake line plus hose carefully for any kind of damages or wear among other issues. Other extra tasks include removal of drum coverings on rear drum brakes; washing out behind it; making sure that lining now meets prescribed standards; inspecting thoroughly all elements found inside drum assembly particularly spoilt fluid spots. A procedure for examining boosters is provided together with a parking method involving placing a vehicle on a steep slope with a set parking brake while leaving transmission at neutral position to ascertain if it would stop rolling down hill even though engine was not running.

To do an operating check, apply the brake pedal several without starting the engine and engine off to pocket check if there is any variation on the reserve pedal distance then Start the engine and check if the brake reduces slightly. For the airtightness check, switch on the engine and switch it off after one or two minutes then change the brake pedal gently several times; if the depression decreases each time, the booster is leak proof. With the engine running, push down the brake pedal and shut down the engine with the pedal depressed; if after holding it for 30 seconds there would be no return mark on the pedal, the booster is also airtight. When disconnecting the power brake booster units do not disassemble all the components as they are intricate, and require special instruments to assemble, get new or rebuilt ones. First, one must detach the brake master piston after which, for some models, it will be necessary to completely disconnect brake lines crossing in front of the master cylinder. Safely unplug vacuum hose from the brake booster, further, take out the brake pedal return spring at the top of the brake pedal, the clevis pin retaining, and the pin. Fourthly, unlock the four bolts that connected the brake booster to the fire wall and pull out the booster forward till the studs are out of the holes. To install the equipment, it will be done in the reverse manner of the removal process while making sure that the booster mounting nuts have been tightened to the right torque. Some of the procedures include; adjusting the brake pedal height and free play, and bleeding the system if necessary once the master cylinder and brake hoses have been fitted.
