Brake pads are an integral part of anycar. On cars of mark "Renault Logan" the brake system of the combined type is established. So, in front you can see the disk elements, and behind - the drum. Pads are equated to consumables, therefore from time to time the machine needs replacement of back blocks. "Renault Logan" 1.4 is no exception. Today we will tell you when and how to change these items on Renault Logan cars.
Resource pads - a very controversial topic for conversation. After all, their life span is affected by many factors - driving style, car load, its curb weight and road conditions.
Also note the fact that the front padshave a resource of 2 times lower than the rear. The last serve for 50-100 thousand kilometers. This is due to simple physical factors - when braking, the load is applied to the front axle. How to determine if a car needs a replacement of the rear pads? "Renault Logan" is equipped with drum mechanisms, which are hidden behind the metal cover. Therefore, it is not possible to visually determine the wear of friction materials, as is the case with front disc calipers.
Therefore, you need to be guided byregulations of replacement and the behavior of the car. If the car has become worse braking, while holding the handbrake badly (namely, it clamps the rear drums), then the car requires replacement of the rear brake pads. "Renault Logan" 1.4 may also require repair in case of oiling of friction linings or material peeling.
What do you need to replace? During the work we will need the following tools:
Without what else is it necessary to replace the rear pads?"Renault Logan" will additionally require a nebulizer to clean the pads. You will also need a piece of wire, a brake fluid reservoir and a universal lubricant VD-40. Since we will work with chemicals, we need to prepare rubber gloves.
Do not forget to prepare and wheel stops.To replace the rear shoes you need to turn off the parking brake. To prevent the machine from moving forward in the posted state, place two “shoes” under the front wheels (a construction brick will be suitable from the available tools).
Replacing parts such as brake pads,performed in pairs. That is, in the course of the work, we need to install 4 new pads, 2 on each side. Is it possible to partially replace the rear brake pads? "Renault Logan" 1.6 will lead away to the side in any attempt to reduce speed. Therefore, the pads are changing in full.
So, how does the replacement of the rear shoes begin?"Renault Logan" 1.6 is installed on the jack (do not forget about the stops). You must first loosen the bolts of the wheel. Then it is necessary to process the protective cap of the drum with liquid VD-30 and remove the ABS sensor (if the car was equipped with this). After that, the hood is opened and the level of brake fluid in the tank is checked. It must be drained to the middle mark. Next head "30" scrolls the nut in the drum. Please note that when replacing the left pads nut unscrew counterclockwise. In the case of the right, everything is exactly the opposite. How next is the replacement of the rear brake pads? Renault Logan continues to stand still, while we proceed to dismantle the brake drum. Next, we take into the hands of a special spray solvent and process them old brake pads.
Now you can finally remove the pads.Using a piece of wire is required to pull the brake piston. After that, we apply silicone grease on the ribbed protrusions (where the shield touches the pads). Motorists recommend using the tool "PentaSIL". It provides lubrication at temperatures up to 250 degrees Celsius. Before installing the new pads, the retaining ties must be removed. How further is the replacement of the rear brake pads? Renault Logan is equipped with new friction linings. Below we will look at the assembly algorithm in detail.
The first thing you need to thoroughly purge andclean all connecting parts and knots of the drum mechanism. After installing the pads, you must replace the upper spring. It is mounted short part to the right. Next, set the adjusting bolt. A second spring is put on the right side. The pads finally "start up".
The upper and lower springs are mounted onspecial hooks. Next, you need to install the cotter pins ("soldiers") on the back side of the casing and install the brake drum. However, to do this, you need to push the pads as much as possible. How? Using a screwdriver, you need to turn the drum in the upper part of the mechanism. The drum cover should fit tightly into the seat. At the same time, it should be slightly in contact with the pads during the rotation of the disc. Tighten the drum cap nuts finally. Do not forget to add brake fluid.
How is the rear pads replaced?"Renault Logan" goes down with a jack. At the end of the stub nut twists. Experts recommend using a torque wrench. The nut on the rear wheel hub "Renault Logan" is tightened with a force of 180 to 210 Nm. In the absence of such a tool will have to put everything on the eye. So, the nut is twisted until there is a slight play on the wheel. The disk should “walk” a little if you shake it from side to side. Be careful: if you retighten the nut, the wheel bearing may fly apart. Installing a new one will cost you 5 thousand rubles without taking into account the work.
So, we figured out how to produceself-replacement rear pads. Renault Logan is a very maintainable French car. Therefore, most repair operations can be performed with our own hands. In the case of the front pads, the situation is even simpler. To replace them, just remove the bracket, remove the old pads from the guides and install new ones in their place. Twist off the hub nut is not necessary.
