Reasons Why the Brake Pedal of Buick Excelle is Hard to Press Down

[MacKennedy]

This situation must be caused by a problem with the vacuum booster pump. Under normal driving conditions, the negative pressure in the intake manifold will draw air from the vacuum booster pump. Here is an introduction to the Buick Excelle: 1. Buick Excelle: The new Excelle adheres to Buick's "dynamic and smooth" design language, drawing inspiration from the classic elements of the Riviera concept car. The body styling is sporty yet stable, presenting a style that is both grand and simple, elegant and dynamic. The new wing-shaped chrome-plated grille, combined with black piano vertical grilles and high-gloss chrome-plated wing grilles, naturally draws the visual focus of the front end to the emblem. At the same time, the wing grille extends horizontally to the headlights on both sides, enhancing the horizontal visual effect and overall sense of the front end. 2. Powertrain: The new powertrain includes a 1.3T+48V mild hybrid engine and the classic 1.5L DVVT four-cylinder engine, comprehensively balancing power, fuel consumption, and a good driving experience. The diverse options meet the needs of different consumers, delivering an efficient and agile power experience.
