How to Replace the Small Brake Discs of Verna with Larger Ones?

Detailed steps for replacing the Verna's brake discs with larger ones are as follows: 1. Check the wear level of the brake discs. During routine maintenance, determine whether to replace the brake discs based on actual conditions. If there are grooves deeper than 3MM on the brake discs, they can be replaced. 2. Remove the front wheel tires. To replace the brake discs, both front wheel tires need to be removed, revealing the round discs which are the car's brake discs. 3. Remove the caliper mounting screws. The brake discs are mounted on the front wheel bearings, secured by the brake caliper from the outside. Remove the two 18mm screws on the caliper, then carefully lower the caliper to prevent damage to the brake line. 4. Remove the old brake discs. The old brake discs are mounted on the front wheel bearings, and rust may form between the bearings and the brake discs. Use a hammer to gently tap the back of the brake disc while rotating it to remove the old brake discs. 5. Install the new brake discs. Align the holes on the new brake discs with those on the bearings, then lightly tap the inside of the brake discs with a hammer to ensure they are securely fixed to the bearings. 6. Reinstall the brake caliper. Mount the caliper back in its original position, tighten the two mounting screws, and rotate the bearings to check for any unusual noises.

I think upgrading to larger brake rotors on the Verna requires safety considerations first. Directly installing bigger brake rotors necessitates matching larger calipers, and the original brackets may not fit. You'll need to find vehicle-specific upgrade kits or use adapter bridge brackets for proper fitment. After modification, brake force balance testing is essential to avoid pulling during emergency braking. By the way, upgrading to larger wheels is often necessary too, as the new rotors might not clear the stock wheels. I recommend going to a professional tuning shop - they can test brake fluid pressure and replace the steel braided hoses simultaneously for better system integration. DIY attempts could be risky, safety always comes first.

My friends who are into car modifications shared some interesting experiences about upgrading the brake discs on the Verna. First, you need to measure the dimensions of the original wheel bearing flange, then find a matching larger diameter disc. The key point is pairing it with a suitable new caliper—many opt for four-piston racing versions for better heat dissipation. During installation, pay attention to the torque specifications; every bolt must be tightened to standard. After that, it's essential to bleed the brake lines thoroughly—I once didn't remove all the air bubbles, resulting in spongy brakes. Post-installation, you must perform low-speed repeated braking to bed in the new discs, otherwise, uneven contact surfaces can cause vibrations. It's also advisable to upgrade the brake fluid simultaneously; DOT4 or higher performs better under high temperatures.

If you're on a tight budget, try keeping the original calipers and only upgrading to slotted and drilled rotors. However, the diameter increase is limited due to the fixed caliper opening size. I've seen people at auto parts markets use wheel spacers to push the wheels outward, allowing slightly larger rotors to fit. But this puts extra strain on the bearings and may cause noise over time. Actually, just upgrading to good quality brake pads with your stock rotors works well enough - last time I switched to ceramic pads and saw significant braking distance reduction. If you insist on larger rotors, be prepared to spend around two thousand for the whole setup.
