Airbag Under the large impact plate in the middle of the steering wheel, or above the glovebox, there is one airbag each, which is inflated in crashes by igniting a...
Independent work on the brake system In equipment as important as the brake system, no control can be redundant! And if you keep order in this area, then you will perform maintenance work better...
How the braking system works When you depress the brake pedal, a pushrod connected to the pedal presses two pistons arranged one behind the other into the brake master cylinder (rear left...
Brake check Constant control Test full braking at walking speed first. By the same rubber marks on the road, you will see that the brakes pull the same way. This also...
Brake fluid The fluid in brake hoses and brake cylinders is a mixture of glycol, polyglycol ether and a few other elements. This yellowish liquid is poisonous and...
Checking the brake fluid level Constant control On the left rear in the engine compartment, right on the master brake cylinder, there is an expansion tank with brake fluid. In a transparent...
Checking the brake system for leaks and damage Maintenance work When performing this test, the underside of the vehicle must be dry so that you can see leaks. Brake fluid also spreads under the dirt. Places...
Brake Fluid Replacement Maintenance work Changing the brake fluid is required not only because of the risk of vapor formation mentioned above, but also because of the risk of...
Disc brakes In the air flow, a steel disk rotates freely along with the wheel. So-called brake calipers saddle around the discs. When you press the brake pedal, the...
Checking the brake pedal travel Maintenance work If over time the pedal travel lengthens, then it can be assumed that there is a malfunction in the brake system: With the engine running,...
Measuring front disc brake pads Maintenance work The piston pushes the wearable brake lining so far that it is only a fraction of a millimeter from the brake disc. Therefore, brake pedal free...
Checking the condition of the brake discs Maintenance work If the front wheels are removed to inspect the brake pads, the condition of the brake discs is also checked. The discs should not have deep...
Replacing the front brake pads Both linings should always be changed on the right and left. Only use pads with ABE. Because The pistons in the brake calipers protrude more and more as the...
Rear disc brakes On the rear axle of the Vectra with a 16V engine are disc brakes. Unlike the front wheels, which have floating caliper disc brakes, the rear wheels are fixed...
Measuring rear disc brake pads Maintenance work Checking the wear of the rear disc brake pads is carried out in the same way as on the front brakes. Here, too, the minimum dimension is 6 mm...
Drum brakes The Vectra with a 1.6-liter eight-valve engine has drum brakes on the rear axle. In this brake design, two brake pads are pressed by the pistons of the wheel...
Measuring drum brake pads Because If the running shoe wears out faster than the rear pressing shoe, then the thickness measurement is made only on the front shoe. Raise the rear of the...
Hand brake When you apply the handbrake, the brake cables are pulled towards the rear wheels. As a result of this, the brake lever of the secondary shoe located at the...
Checking the handbrake Maintenance work If the parking brake is applied vigorously each time you park, the brake cables will lengthen over time. But, on the other hand, someone who...
Hydraulics and control After we have familiarized ourselves with the mechanical part of the brake system, we now turn to the control of the brake system with its hydraulic assemblies...
Work on the hydraulic braking system Working Technique Tips Brake fluid is poisonous. Do not allow it to come into contact with your mouth. Brake fluid corrodes car paint. Therefore, do not place...
Master brake cylinder Removing the brake master cylinder To a certain extent, the master brake cylinder is the main element of the brake system. It is located at the rear left in...
Brake booster Disc brakes, unlike drum brakes, do not work with a self-reinforcing effect: they require significantly more pedal force. Therefore, the Vectra has an air...
Checking the brake booster Maintenance work The engine must be off. Press the brake pedal 10 times. Now keep the pedal fully depressed and start the engine. If the brake booster is...
Bleeding the brake system The brake system must be bled after the repair of the hydraulic drive, if air enters the brake cylinders and brake pipes. Completely fill the expansion tank...
ABS can not do everything! ABS cannot create a braking miracle, as is often assumed; the braking distance will not, under any circumstances, become significantly shorter. To a greater...
What does ABS do? ABS always provides optimal «intermittent braking», so pure blocking braking is no longer possible. The wheels on smooth ice, even with full braking, still...
Functions of individual nodes Hydraulic module It is located on the left in the engine compartment: the module is installed between the brake pipes from the master brake cylinder and the...
Malfunctions in the anti-lock system When the ignition is switched on, the ABS warning lamp on the dashboard flashes. It should go out when the engine starts or no later than reaching a speed of 5...
Traction Control System Behind this English name lies the traction control, which is standard on Vectra models with a displacement of 2.0 liters. Thanks to the traction control, the...
