Step-by-step replacement of the rear brush with Octavia A7 (with photo)

You can replace the brush in 3-5 minutes without tools. The main thing is not to break the plastic fastener. Follow the instructions:

1. Raise the wiper to the vertical position (perpendicular to the glass). On Octavia A7 it locks in this position automatically.
2. Press the plastic clip at the base of the brush (it is located on the side, on the driver’s side). Use a flat head screwdriver if you can't do it with your fingers.
3. Slide the brush downto remove it from the hook. Do not pull to the side - this can bend the metal lever!
4. Install a new brush, aligning the groove with the hook, and snap the latch until it clicks.

If the brush does not lock or is loose, it means that you have not aligned the groove with the hook correctly. Don't use force — it’s better to check the compatibility of the fasteners again.

Why a new brush doesn’t clean well: 4 hidden reasons

Did you buy an original brush or a top-end one? Bosch, but it still leaves streaks or creaks? The problem is not always the quality of the rubber. Here real reasons and ways to eliminate them:

• 🧴 Dirty glass: There may be a film of wax or silicone on the surface (for example, after washing). Wipe the glass white spirit or a special glass cleaner.
• ❄️ Ice in the mechanism: If the wiper does not move smoothly, check to see if the guides are frozen. Pour warm water (not boiling water!) over the mounting area.
• 🔩 Lever wear: Over time, the metal wiper arm bends and the blade does not press against the glass. The solution is to bend the lever with pliers (carefully!).
• 🛠️ Incorrect installation angle: If the brush is positioned crookedly, it will “bounce”. Check that the groove on the brush sits tightly on the hook without play.

A secret from service station masters: to make your brush last longer, treat it with silicone grease once a month (for example, WD-40 Specialist). This will prevent the rubber from cracking and reduce friction.

How to extend the life of your rear brush: 5 proven methods

Average rear brush life Octavia A7 — 6–12 months. But with these tips you will increase it to 2-3 years:

1. Wash your brush once a week soap solution (not aggressive detergents!). This removes abrasive particles that wear down the rubber.
2. Do not operate the wiper on dry glass. Always spray the glass with glass cleaner or water first.
3. Park in the shade. Ultraviolet radiation destroys rubber. If you don't have a garage, cover the brush with a cover (sold at AliExpress for 200–300 rubles).
4. Clean the ice manually in winter. Do not wait until the wiper “breaks through” the ice crust - this kills the tires in 1-2 weeks.
5. Use winter brushes (for example, Bosch Winter). They are softer and do not tan in the cold.

⚠️ Attention: Never use solvents (acetone, gasoline) to clean the rubber of the brush - they destroy its structure. Only soap solution or special car shampoos.

What happens if you ignore the squeaking of the brush?

Constant squeaking is a sign that the rubber of the brush is worn out and is scratching the glass. If you do not replace the brush on time, microcracks will appear on the glass, which will eventually turn into chips. This is especially dangerous in winter, when cracks can grow due to temperature changes.

Common replacement mistakes and how to avoid them

Even experienced drivers sometimes make mistakes that lead to windshield wiper failure or glass damage. That's it can't do:

• 🔧 Apply force when removing the brush. If it does not come off, it means you did not press the latch. Don't break the plastic!
• 🧊 Use boiling water for defrosting. Sudden temperature changes can crack the glass.
• 🛒 Buy brushes by eye. Even if the length is the same, the fastening may differ.
• 🚗 Drive with dry glass with the wiper on. This wears out the rubber in 1-2 days.

• 🔋 Fuse status F36 (10A) in the block under the steering wheel - it is responsible for the rear wiper.
• 🔌 Contacts on the wiper motor (they may oxidize).
• 🛠️ There is play in the lever - if it dangles, the brush will “bounce”.
