Nissan Almera Classic (also known as Nissan Sunny B10 in some markets) is one of the most popular sedans in the budget segment, but its rear drum brake system is often a source of problems. Squeaks, vibrations when braking, or increased pedal travel can all indicate worn or damaged rear drums. Unlike disc brakes, drum mechanisms require more thorough diagnostics due to their closed design, where wear on the pads and the working surface of the drum is not always visually noticeable.

In this article we will look at signs of rear drum problems, we will describe in detail the process replacement and repair, and also give recommendations on the selection of spare parts. We will pay special attention unique feature Almera Classic: compatibility of drums with other models Nissan (For example, Primera P11 And Sunny B14), which allows you to save on original parts without losing quality. If you are planning a DIY repair, here you will find step-by-step instructions with photos, spare parts numbers and tips for avoiding common mistakes.

Signs of rear drum failure: when to sound the alarm

Rear drums Nissan Almera Classic wear out gradually, and their malfunctions are often disguised as other problems in the braking system. Here are the key symptoms that should alert you:

  • 🔊 Creaking or grinding when braking - indicates critical wear of the pads or the working surface of the drum. If the sound occurs when driving without pressing the pedal, the problem may be in the wheel bearing.
  • 🌀 Vibration on the brake pedal or steering wheel - a signal about the deformation of the drum (the so-called “beating”). Often occurs after overheating or aggressive braking.
  • 🚗 Pulling the car to the side when braking - may indicate uneven wear on the drums or pads on the right/left side.
  • 🛑 Increased brake pedal travel — a sign of pad wear or oil/dirt getting on the working surface of the drum.
  • 🔥 Overheating of the rear wheels after a trip - indicates jamming of the brake mechanisms (a soured handbrake cable is often to blame).

Feature Almera Classic — no pad wear sensors on the rear axle (as opposed to front disc brakes). Therefore, diagnostics have to be carried out manually, removing the drums for visual inspection. If you notice at least one of the listed symptoms, you cannot postpone the check: worn drums increase the braking distance and can lead to wheel jams.

⚠️ Attention: If, after replacing the pads or drums, the brake pedal becomes “soft” and does not return to its original position, immediately check the tightness of the brake cylinders. On Almera Classic The rubber cuffs of the rear cylinders often fail, which leads to brake fluid leakage.

Step-by-step instructions: how to remove and replace the rear drum with Almera Classic

Replacing rear drums with Nissan Almera Classic requires a minimal set of tools, but has several nuances. The main thing is remove the drum correctlywithout damaging the wheel bearing. Here are the detailed instructions:

Required tools:

  • 🔧 Set of sockets and ratchet wrench (sizes: 10, 12, 14, 17 mm).
  • 🔨 Hammer with a rubber striker (for removing the drum).
  • 🔩 WD-40 or equivalent (for unscrewing soured bolts).
  • 🔧 Brake drum puller (optional, but simplifies the work).
  • 🛠️Pliers and a flat blade screwdriver.

Work order:

  1. Preparation: Jack up the rear of the car, remove the wheel and release the handbrake. Be sure to block the front wheels with chocks!
  2. Removing the brake drum:
    • Unscrew the guide pins (2 pcs.) using a socket on 12 mm.
    • If the drum does not come off, gently tap it on the back side with a rubber mallet. Don't hit the hub!
    • If there is strong sticking, use a puller or evenly tighten the studs into the holes of the drum (if any).
  3. Inspection and replacement:
    • Check the condition of the pads, springs and brake cylinder. If there are oil stains on the pads, look for a wheel bearing or cylinder leak.
    • Install a new drum, having first cleaned the seat from rust and dirt.
    • Tighten the guide pins to torque 25–30 Nm.
  • Adjustment: After installation, adjust the gap between the shoes and the drum using the eccentric mechanism (located on the rear side of the brake shield).

    • Check the condition of the wheel bearing (no play allowed)|

    If the drum is difficult to remove, do not use excessive force as this may damage the bearing. As a last resort, use a penetrating lubricant and give it time to work (10-15 minutes).

    ⚠️ Attention: On Almera Classic With ABS, when removing the drum, a speed sensor error may be activated. After replacement, be sure to reset the errors using a scanner or by disconnecting the battery terminal for 10 minutes.
    💡

    If the drum is “stuck” to the hub, try the “heating” method: point a hair dryer at the joint for 2–3 minutes. The metal will expand, making the drum easier to remove. Do not use open fire!

    Grooving vs replacement: which is more profitable and when is it permissible?

    Many owners Nissan Almera Classic are faced with a dilemma: sharpen the drums or buy new ones? Grooving is cheaper (from 800 rubles per pair), but is not always justified. Here are the selection criteria:

    When a groove is allowed:

    • ✅ The thickness of the drum after grooving will be no less 188 mm (minimum permissible value for Almera Classic).
    • ✅ There are no deep furrows or cracks on the working surface.
    • ✅ The drum is not deformed (checked by a beat indicator).

    When only replacement:

    • ❌ Drum thickness is less 190 mm (risk of overheating and cracking).
    • ❌ Presence of radial cracks or chips.
    • ❌ Strong beating (more than 0.15 mm), which cannot be removed by grooving.

    Cost of grooving in the service - 800–1 500 ₽ per pair, but remember: after grooving, the life of the drums is reduced by 30–40%. If you plan to use the car for longer than 2-3 years, it is better to immediately install new parts.

    For grooving at home, you can use an attachment on a drill or lathe, but without experience it is easy to damage the drum. The best option is to contact a turning workshop, where the work will be performed on a CNC machine.

    💡

    Drum grooving is justified only if there is minimal wear and no deformation. In other cases, replacement is more reliable and safer.

    Common mistakes when replacing rear drums and how to avoid them

    Even experienced car owners make mistakes when working with rear drums Nissan Almera Classic. Here are the most common ones and ways to prevent them:

    1. Improperly tightened guide pins:

      If you tighten the studs, the drum will become deformed; if you don’t tighten them enough, vibration will appear. Use a torque wrench and torque 25–30 Nm.

    2. Ignoring the condition of the brake cylinders:

      On Almera Classic rear cylinders often leak after 100–150 thousand km. If there are traces of brake fluid on the pads or drum, the cylinders need to be replaced.

    3. Lack of pad adjustment after installation:

      If you do not adjust the gap between the pads and the drum, the brakes will jam or operate ineffectively. The adjustment is made by the eccentric on the brake shield.

    4. Using incompatible pads:

      The pads must match the drum in radius and material. For example, ceramic pads are incompatible with cast iron drums - this will lead to accelerated wear.

    5. Forgetting to lubricate the guides:

      If you do not lubricate the studs and the seat, the drum will “stick” to the hub the next time it is dismantled. Use graphite or copper grease.

    Another typical problem is incorrect assembly of springs and spacers. If, after replacing the drum, the pads do not move apart or brake constantly, check that all elements are installed correctly. The assembly diagram is usually in the repair manual. Almera Classic.

    What happens if you don't adjust the pad clearance?

    An unadjusted gap leads to two problems:

    1. Brake jamming — the pads constantly rub against the drum, overheating it and increasing fuel consumption.

    2. Reduced braking performance — if the gap is too large, the brake pedal becomes “wobbly” and the braking distance increases.

    On Almera Classic adjustment is carried out manually using an eccentric mechanism on the brake shield. After replacing drums or pads, adjustment must be carried out!

    How to extend the life of rear drums: operating tips

    Rear drum service life Nissan Almera Classic depends not only on the quality of the parts, but also on the driving style. Here are some tips to help avoid premature wear:

    • 🚦 Avoid prolonged braking at high speed - this leads to overheating of the drums and deformation. Use engine braking on descents.
    • 🔧 Check the condition of the handbrake cable regularly - if it sours or is overtightened, the pads will jam, accelerating the wear of the drum.
    • 💧 Monitor the brake fluid level — its leakage from the rear cylinders leads to contact with the pads and drums, which causes corrosion.
    • 🚿 Wash your brakes when replacing wheels or once every 20 thousand km. Use special cleaners (for example, Liqui Moly Bremsen-Reiniger).
    • ❄️ Avoid sudden braking on wet or icy roads - this increases the load on the drums and can lead to their deformation.

    Also note brake pad quality. Cheap friction materials (especially those with a high metal content) quickly wear out drums. The best choice for Almera Classic — pads in the mid-price segment from Ferodo, Textar or TRW.

    If you frequently drive off-road or in high humidity conditions, it is recommended that you remove the drums once a year for inspection and cleaning of dirt. This will prevent corrosion and jamming of mechanisms.

    FAQ: Frequently asked questions about rear drums Nissan Almera Classic

    Is it possible to install disc brakes instead of drum brakes? Almera Classic?

    Technically this is possible, but it will require serious modifications:

    • Replacing the rear beam with a model with disc brakes (for example, from Nissan Almera N16).
    • Installing a new master cylinder and brake force regulator.
    • Modification of brake lines.

    The cost of such tuning exceeds 50–70 thousand rubles, so for most owners it is impractical. An exception is preparing a car for sports disciplines.

    How often should rear drums be replaced? Almera Classic?

    The service life of the drums depends on the operating conditions:

    • In city mode (quiet driving) - 150–200 thousand km.
    • For an aggressive driving style or frequent trips on mountain roads - 80–120 thousand km.
    • When using cheap pads - 60–100 thousand km.

    It is recommended to check the condition of the drums every 30 thousand km or when replacing pads.

    Why does the car brake jerkily after replacing the drums?

    The reasons may be as follows:

    • Unadjusted gap between the pads and the drum.
    • Deformation of the new drum (defective or damaged during installation).
    • Uneven pad wear (for example, if old pads have not been replaced).
    • Dirt or grease on the working surface of the drum.

    Solution: Remove the drums, check the pads and adjust the clearance. If the problem persists, check the drum runout with an indicator.

    Is it possible to drive if the drum is cracked?

    Absolutely not! A crack in the drum is a risk of its destruction at high speed, which will lead to complete loss of brakes on one of the wheels. Even a small crack requires immediate replacement of the drum.

    If a crack is discovered during a trip, drive at a speed no more than 40 km/h and avoid sudden braking until you get to the service station.

    Which brand of drums is better to choose for Almera Classic?

    Optimal options in terms of price/quality ratio:

    1. TRW (GDB1440) is the best choice for most owners. Good quality at a reasonable price.
    2. ATE (24.0120-0166.2) - premium segment, suitable for intensive use.
    3. Brembo (09.6498.11) - maximum resource, but the price is higher than average.

    Budget analogues (Fenox, ABS) are only suitable for quiet driving and require more frequent replacement.
