Likewise, how do you diagnose a bad coil spring? Here are a few symptoms that will let you know if your coil springs have worn out.Īs the name ( strut mount) implies, it's a component that attaches the suspension strut to the vehicle. Spring insulators are not the most obvious element in your suspension, but their role is pretty important.Ĭoil spring isolators, also called coil spring dampeners, are used between the windings of the coil springs to expand the spring and return a vehicle to its original ride height while lessening the effects of coil spring sagging. Their job is simple – they help to insulate the car against vibrations, jostling and more.

We install the vacuum amplifier in reverse order.īefore installation, you need to check the dimensions of the amplifier, and if necessary, restore them by rotating the adjusting bolt of the amplifier rod.These are small, rubber pieces that are mounted at the top and bottom of the coil springs. Unscrew the four nuts securing the vacuum brake booster to the front panel

Squeezing the plastic locking ring, we remove the finger from the holes of the pedal and the pusher fork

We pry with a screwdriver and remove the two holders of the sound insulation liningĭisconnect the pusher of the vacuum booster from the brake pedal, for which we detach the spring lock of the finger from the pedal We pull the main cylinder forward without disconnecting the brake tubes from it Unscrew the two mounting nuts of the main brake cylinder, as described above. Install the main brake cylinder in reverse order.įill the brake fluid into the tank and pump the brake system (Replacement of brake fluid and pumping brakes Renault Sandero) Replacement of the vacuum brake boosterĭisconnect the check valve with the connected hose from the vacuum amplifier The flange of the brake cylinder is sealed with a rubber ring. Unscrew the two nuts securing the main brake cylinder to the vacuum booster Jamming the holes of the brake tubes in the available ways. Unscrew the nuts of the attachment to the cylinder of the four pipelines and pull the tubes aside.įor clarity, the tank of the main brake cylinder has been removed. You will need a special key for 11 brake tubes and a key for 13. Installing the tank in reverse order Removing the main brake cylinder Using a screwdriver, we remove the tank, removing its nozzles from the connecting tubes

We pump out the brake fluid from the tank with a rubber bag or a syringe Removing the brake master cylinder tankĭisconnect the wire from the negative terminal of the batteryĭisconnect the wiring block from the brake fluid level sensor If this does not happen, then the vacuum amplifier or the check valve of the vacuum amplifier does not work, and the vacuum amplifier hose may also not be sealed. Holding the brake pedal in the pressed position, start the engine. When the engine is not running, we press the brake pedal five or six times on the brake pedal. If the force on the brake pedal has noticeably increased during braking, you need to check the amplifier on a stationary car. If the vacuum booster is faulty, the force on the brake pedal increases significantly. The vacuum brake booster is replaced when it fails. the compensation holes are clogged (spontaneous braking of the car occurs) wear or damage to the piston cuff of the main cylinder contamination of the main cylinder or a large wear of its mirror The main cylinder of the brakes and the vacuum brake booster are replaced in case of defects.ĭefects of the main brake cylinder, which should be repaired or replaced:
