"Chevrolet Lacetti" is a budget car, which is often found on the roads of Russia, Europe and the USA. Car enthusiasts choose sedans, hatchbacks and station wagons for their reliable engine and simple suspension design. Repair and maintenance is most often carried out in garage conditions with the help of reference books and other supporting literature. Many users are concerned about the issue of replacing brake discs in the Lacetti and servicing the entire system as a whole.
Description of the vehicle
Chevrolet appeared in Russia in 2002 and gradually began to gain an audience of fans and happy owners. Italian engineers worked on the design, and the power plants were inherited from Daewoo and Opel.
"Lacetti" got quite a classic body with smooth lines and easily recognizable features. In 2004, there was a slight restyling, which touchedhead optics, radiator grille and engine settings. Sedan, hatchback and station wagon are very different from each other in the design of the front and rear optics, as well as in size.
The salon turned out to be modest without pronounced design frills. The basic equipment includes heated side mirrors, an airbag for the driver, electric front windows and a central locking system with an immobilizer. The multimedia system, air conditioning and heated front seats will have to be paid separately.
Russian versions are offered only with petrol engines of 1.4 and 1.6 liters with a maximum power of 95 and 109 horsepower. The power plant works with an automatic transmission with 4 steps or a 5-band "mechanics".
Brake system
"Lacetti" is equipped with a classic two-circuit system with separation of the diagonal wheels. When fully operational, both circuits are involved, and in the event of a breakdown or unexpected failure, braking is carried out by one circuit. With one circuit, the braking distance is significantly increased, because only two wheels are used to stop.
The front wheel mechanism consists of ventilated discs and a floating caliper with a single piston caliper. The bracket is attached with two screws to the hub, and the movable caliper is held on special guides. The front brake discs in the Lacetti can last up to 60,000 kilometers, depending on driving style.
The rear brake system is similar to the front brakes except for smallerdimensions of components and brake disc. The disk is made without special grooves for ventilation and plays the role of a drum for a hand brake, which is installed inside. The rear brake discs in the Lacetti easily nurse up to 150,000 kilometers.
Versions with the ABS system have an additional unit under the hood and speed control sensors in the hubs. During emergency braking, the unit receives data from each sensor and adjusts the braking force on the wheels. In the event of a failure of the electronic systems, the brakes remain fully functional. Brake discs in the Chevrolet Lacetti do not affect the performance of the ABS unit.
Original brake discs
The front brake disc is 256mm in diameter and 2.4cm thick. The front brake discs in the Chevrolet Lacetti wear out seriously at the turn of 60,000 kilometers. Original components are afraid of sudden temperature changes and often warp when hit in a puddle after hard braking.
The front and rear discs are not painted with a special composition, so a year after purchase, you can find pockets of corrosion on the ends and in places adjacent to the hub. The resistance to overheating also leaves much to be desired - often after an active trip, blue stripes are observed on the working surface.
The front and rear original brake discs in the Chevrolet Lacetti cannot always provide the declared stopping distance, so owners often change components to similar ones fromthird party manufacturers.
Third Party Drives
Parts made in branded factories are able to give the best results in terms of braking and resistance to overheating. To select suitable items, you need to provide the VIN number to the seller or enter it in a special window on the online store page. The body number is indicated on a plastic card, which is a certificate of registration, or in the vehicle's passport.
When choosing brake discs for the Chevrolet Lacetti, you should pay attention to well-known companies:
- Bosch;
- Ferodo;
- TRW;
- Lucas;
- Brembo;
- ATE;
- Otto Zimmermann.
All listed models are available for both front and rear axles. The composition of the metal includes chemical components that prevent premature corrosion. Disc ventilation holes have also been changed, making it much more difficult for the brake system to heat up.
How to determine the status of components
The following parameters indicate the wear of the brake system:
- Perceptible beating in the steering wheel when braking;
- squeaks, "crunches" and other extra sounds when you press the brake pedal;
- perceptible reduction in the efficiency of the braking system;
- bad smell around the car and hot alloy wheels after a long drive.
Condition is also determined by visual inspection. Concern can be a pronounced edge that indicates wear, deep scratches, microcracks and corrosion.
How much does it cost to replace discs in a car service
Brake discs in the "Lacetti" (front) are changed in tandem with the pads, in addition, it may be necessary to replace the caliper guides and torn rubber bands.
The official dealer offers a service for replacing disks for 3000-5000 rubles. The cost of original parts will cost at least 10-12 thousand rubles. Additional adjustment of the camber and convergence is not required, since the adjustment bolts are not involved in the replacement process.
Rear original components will cost a little cheaper - from 6-8 thousand rubles. The cost of the work is estimated at the same 3-5 thousand.
Self-replacement
Do-it-yourself work will require a set of tools, copper grease and a special compound for guide calipers.
To replace the front discs, you need to follow the steps in sequence:
- Remove the wheel.
- Unscrew the 2 bolts that hold the caliper, then remove it.
- Hang the caliper onto the rack cup with wire or rope.
- Remove pads.
- Unscrew the 2 bolts that hold the bracket.
- Remove the old brake disc by unscrewing 1 screw.
- Clean the hub from dirt with a brush, evenly distribute copper grease and install a new disc.
- Assemble all parts in reverse order.
When carrying out work, do not forget aboutcaliper guides. They need to be cleaned of old grease and applied with a new composition. TRW PFG-110 is great for guides.
The rear brake discs in the Chevrolet Lacetti are changed in a similar way, no additional tools are required. When replacing, the vehicle must be released from the handbrake.
Reviews from car owners about the Lacetti brake system
Users don't change brake components often, which means the system is highly reliable. However, with active driving, regular brakes often overheat, this is accompanied by an unpleasant smell from the pads and a significant increase in braking distance.
The solution to the problem is to install pads and discs from third-party manufacturers. The ABS system and the directional stability function work without failures and errors. Blocks do not require replacement even with a mileage of over 300,000 kilometers.
