The braking system is the foundation of the safety of any car, and the Nissan Almera is no exception. In city traffic jams and frequent stops, the front brake pads wear out the fastest, since they account for up to 70% of the braking force. Ignoring signs of wear can lead to brake rotor damage and, even more dangerous, brake failure in a critical situation.
Many owners Nissan Almera they try to postpone a visit to the service, hoping that the creaking or vibration will go away on its own. Unfortunately, this misconception only increases the cost of repairs. Timely replacing front pads - this is not just a technical procedure, but an investment in your life and the safety of expensive suspension components.
Signs of wear and diagnostics of the brake system
You can determine that it is time to change consumables by a number of characteristic symptoms that cannot be missed if you drive carefully. The most obvious signal is the appearance of a metallic grinding sound when you press the brake pedal. This sound occurs because the friction layer has worn out and the metal base of the pad begins to rub against the disc.
In addition to noise, it is worth paying attention to the behavior of the car when braking. If Nissan Almera starts to pull to the side, or the brake pedal becomes too soft and falls out, this is a sure sign of problems. The brake pad wear indicator may also light up on your dashboard if your vehicle is equipped with a brake pad wear indicator.
- 🔊 The appearance of a characteristic metallic grinding or squeaking sound when braking.
- 📉 Increasing the length of the braking distance with the usual pedal effort.
- 📉 Vibration of the steering wheel or body during sudden deceleration.
Visual diagnosis is the most accurate method of assessing the condition. To do this, it is not necessary to remove the wheel completely; just look through the spokes of the rim. If the thickness of the friction lining is less than 3-4 millimeters, the operation of the vehicle becomes dangerous.
Selecting the right consumables for Almera
The auto parts market offers a huge range of brake pads, and choosing the right manufacturer is 50% of the success of the entire operation. Original parts Nissan always have guaranteed quality, but their price is often too high, and their service life may not be the longest depending on operating conditions.
For those who are looking for the optimal price-quality ratio, it is worth considering proven analogues from global brands. Companies like TRW, ATE or Brembo produce components that often even exceed original wear resistance and braking performance.
It is important to consider that cheap Chinese analogues can not only quickly wear out, but also damage the brake disc with their abrasiveness. Saving on safety in this case is absolutely unjustified. It's better to spend a little more money on a quality set than to change expensive wheels later.
- 🏆 Original pads Nissan - standard of quality, but high price.
- 🔧 Premium analogues (ATE, Brembo, Textar) - excellent efficiency and long service life.
- 🛡️ Budget analogues (Ferodo, Bremi) are an acceptable option for a quiet ride.
Necessary tools and workplace preparation
Before you begin the replacement procedure itself, you need to prepare all the tools and ensure safety. You will need a standard set of wrenches, a jack and, most importantly, reliable supports (goats). Working under a machine that is only supported by a jack is strictly prohibited.
Removing the caliper usually requires 12 or 14 millimeter wrenches, depending on the model year. Also, do not forget to prepare a container for used brake fluid and a rag to clean parts from dirt and brake dust.
☑️ Preparing to replace pads
Be sure to check the brake fluid level in the reservoir before starting work. When replacing pads, the caliper pistons are pushed back, which forces fluid back into the reservoir. If the fluid level is at the MAX mark, it may overflow when the piston is completely recessed.
⚠️ Attention: Do not press the brake pedal under any circumstances after removing the old pads and removing the piston from the caliper. This will cause the piston to completely come out of the housing and cause a loss of brake fluid.
Why do you need to clean the caliper?
Before installing new pads, you must thoroughly clean the caliper guides from dirt and old grease. If this is not done, the caliper may jam, which will lead to overheating of the disc and uneven wear of the new pads. Use a wire brush and Brake Cleaner.
Step-by-step instructions for replacing front pads
The replacement process is not particularly difficult if you act consistently and carefully. First, lift the front of the car and remove the wheel. Clean any dirt from the caliper using brake cleaner to prevent any abrasive from getting into the new system.
Next, you need to loosen the bolts securing the caliper guides. Usually there are two of them: upper and lower. Unscrew them and carefully move the caliper to the side, hanging it on a wire or hook. Do not allow the caliper to hang on the brake hose as this may damage its internal structure.
Remove the old pads and check the condition of the caliper bracket. If the bracket is deformed or scored, the pads will jam even after replacement. Clean the seats for new parts with a wire brush. Press in the caliper piston into the body using a special tool or clamp. Do this slowly, monitoring the fluid level in the reservoir.
- 🔧 Install new pads into the caliper bracket.
- 🛠️ Return the caliper to its place and tighten the guides to the recommended torque.
- 🔩 Put on the wheel and lower the car to the ground.
After installing all the wheels, be sure to bleed the brake system or at least press the brake pedal all the way down a few times until it becomes firm. This is necessary so that the pistons are pressed against the new pads and there is clearance.
Before driving, check the brakes on a safe section of the road. Avoid heavy braking for the first few kilometers to allow the new pads to get used to the discs.
⚠️ Attention: If the brake pedal sinks to the floor when you first press it, stop immediately. This is a sign that the pistons have not moved out of their working position or that there is air in the system. Check for correct assembly.
Nuances of servicing calipers and guides
Often the reason for rapid pad wear lies not in their quality, but in a faulty caliper. The guide pins should move freely without jamming. If they become sour, the pad will not move away from the disc, which will lead to constant friction and overheating.
Whenever you replace the pads, it is strongly recommended to lubricate the guides with special heat-resistant lubricants. Use only lubricants that are designed for brake systems, such as silicone or copper based. Regular lithol or solid oil will not work here, as they destroy the rubber boots.
It is also worth paying attention to the caliper piston boots. If they are torn, dirt and water can get in, causing corrosion and jamming. In this case, it is better to replace the boot or even the entire caliper assembly if the corrosion is already severe.
⚠️ Attention: Using unsuitable lubricant can lead to swelling of the rubber cuffs and complete failure of the brake mechanism during operation.
Comparison of cost and service life of different brands
For clarity, here is a comparative table of popular brands of brake pads available on the market for Nissan Almera. This will help you make an informed choice based on your budget and driving style.

Common mistakes when replacing yourself
Even experienced drivers sometimes make mistakes that can ruin all their efforts. The most common problem is incorrect installation of brackets or forgetting to remove the shipping plugs from new pads. This can cause the caliper to simply not click into place.
Another common mistake is ignoring cleaning. If you leave old brake dust and dirt on the guides, a new set of pads will last half as long. Also, you should not skimp on lubricants by using cheap analogs that can burn out when heated.
Incorrectly tightening bolts is also dangerous. Too little tightening will lead to vibrations and backlash, and excessive tightening will lead to stripping of the threads or deformation of the bolts. Use a torque wrench if you have one, or tighten to the manufacturer's recommendations.
- ❌ Forgot to remove the protective plugs from the new pads.
- ❌ The guides were not lubricated or the wrong lubricant was used.
- ❌ Didn't check the brake fluid level after replacement.
FAQ: Answers to frequently asked questions
How often do you need to change the front pads on a Nissan Almera?
Service life depends on driving style and road quality. On average, pads require replacement every 30,000 - 40,000 kilometers. Regularly checking the thickness of the lining (minimum 3 mm) will help to avoid an emergency.
Is it possible to change only the front pads without touching the rear ones?
Yes, the front and rear brake systems operate independently. However, it is recommended to check the condition of all pads at the same time. If the front ones are worn out, the rear ones may still be in excellent condition, since the load on them is distributed differently.
What should I do if the brake pedal becomes soft after replacement?
Most likely, there was air left in the system or the pistons were not completely recessed. Press the pedal several times to expel the air and check the fluid level. If the problem persists, the brake system will need to be bled.
Do I need to change brake discs and pads?
Not necessary if the discs do not have deep grooves, cracks and their thickness is not lower than the permissible minimum. However, when the pads are heavily worn (down to metal), the discs are often damaged, and their replacement becomes necessary.
What lubricant is suitable for caliper guides?
Use only special high-temperature brake lubricants (for example, silicone-based or ceramic). Conventional lubricants (Litol-24, Solidol) destroy rubber and cannot withstand high temperatures.
