Driving safety directly depends on the health of your car's braking system. For owners Nissan Almera Classic Regular checks and timely replacement of consumables are the key to confidence while driving. The rear brakes on this model play a critical role in emergency braking and holding the vehicle on an incline.

Many car enthusiasts mistakenly believe that the rear pads wear out much more slowly than the front ones, and put off replacing them indefinitely. However, ignoring wear and tear can result in brake rotor damage, requiring much more expensive repairs. In this article we will analyze the replacement process in detail, paying attention to the specific design of the rear caliper.

Symptoms of wear and preparation for work

The need for replacement can be determined not only by the readings of the on-board computer, but also by characteristic signs in the behavior of the car. If you hear a metallic grinding or whistling sound when you press the brake pedal, this is a sure signal that the friction layer has become thinner to the limit.

It is also worth paying attention to the braking efficiency. If the car starts to wobble when stopping suddenly or the pedal becomes too soft, the problem may lie in the rear wheel assemblies. You shouldn’t wait for smoke or a burning smell to appear; it’s better to diagnose it in advance.

To perform the work efficiently, you will need a certain set of tools and consumables. The standard set includes a jack, a wheel wrench, a set of sockets and a ratchet. Also be sure to prepare a special tool for spreading the caliper pistons.

  • 🔧 Observation wrench (swing) or device for pressing the piston
  • 🧴Brake fluid and brake cleaner
  • 🛡️ Wheel chocks and reliable jack
  • 🧽 Clean rags and brush for cleaning parts

Selection of new components and testing

Before starting work, it is extremely important to choose the right kit brake pads. There are many manufacturers on the market, from budget options to original spare parts. Nissan. The original is usually marked with article number 37010-4M40A, but there are high-quality analogues from brands like TRW or ATE.

When purchasing, carefully inspect the packaging and the parts themselves. The friction lining must be glued to the metal base evenly, without visible gaps or chips. The metal base must be smooth, without traces of corrosion, which could interfere with the correct operation of the mechanism.

Check the package. Some kits already come with new guides and lube, making the process easier. If they are not available, it is better to purchase a special high-temperature grease for calipers in advance so as not to stop during operation.

⚠️ Attention! Make sure the pads you select are the correct shape and thickness. Using incompatible parts may cause the caliper to seize and cause the brakes to fail to move.

Removing the wheel and dismantling the caliper

The process begins with lifting the car. Install Nissan Almera Classic on a level surface, apply the handbrake and chock the front wheels. Loosen the rear wheel bolts, then jack up the car and remove the wheel.

Inspect the brake mechanism. You will see a caliper that is attached to the steering knuckle with two guide bolts. They must be unscrewed using a suitable socket. Be careful not to drop the bolts in the dirt or on the asphalt.

After unscrewing the bolts, carefully remove the caliper housing. Do not let it hang down on the brake hose as this may damage the rubber sheathing. It is best to hang it on a wire or hook to the suspension spring.

  • 🔩 Unscrew the two caliper guide bolts
  • 🔗Hang the caliper to avoid damaging the hose
  • 🧼 Clean the seat from dirt and rust

Specifics of working with the rear piston

Unlike the front brakes, the rear piston is Nissan Almera Classic has a special design. It doesn't just slide out, but requires rotation when pressed. This is due to the handbrake mechanism built into the piston.

If you try to simply push the piston in without rotating, you risk breaking the threaded mechanism inside the caliper. To do this, you need to use a special adapter or a universal set for spreading the pistons, which allows you to simultaneously press and rotate the part.

Rotation must occur strictly clockwise. You will feel resistance, but with the right tool, the piston will smoothly recess into the body. Monitor the level of brake fluid in the reservoir, as when the piston is pressed in, it will be forced back into the system.

⚠️ Attention! It is strictly forbidden to use a pry bar or a flat-head screwdriver to press the piston without rotating it. This is guaranteed to destroy the handbrake release mechanism.

What to do if the piston does not move?

If the piston is stuck or does not press in, do not apply excessive force. Try rocking the caliper slightly or checking to see if the mechanism is twisted. Sometimes preheating the guides helps, but more often the problem is a worn thread inside the piston, requiring replacement of the caliper assembly.-->

Replacing guides and cleaning

After removing the old pads, you need to pay attention to the condition of the guides. The rubber boots on them often crack over time, which leads to moisture and dust getting inside. Dirty guides cause caliper misalignment and uneven pad wear.

Remove the old guides, clean the mounting holes and the rods themselves from old grease and dirt. Use brake cleaner and a brush. Apply new special grease to the guides, making sure that it does not get on the friction linings.

Check the condition of the caliper bracket. It has special stops for the pads, which can become deformed over time. If the bracket shows signs of severe wear or corrosion, it is better to replace or restore it, otherwise the new pads will hang around and make a knocking noise.
