Land Rover Power Brake Booster - Genuine Land Rover SJG000090

Product Information

Your vehicles brake booster is designed to provide power assistance to the braking system. On most cars, the brake booster uses engine vacuum to do this. However, many modern cars use an auxiliary vacuum pump to provide vacuum to the brake booster.

The brake booster is in line between the brake pedal and brake master cylinder. It essentially amplified the force applied to the pedal by your foot and outputs more braking force in the hydraulic braking system. This makes braking your vehicle a much less physical task.

When a brake booster is failing you may notice that braking effort increases. the engine runs poorly or stalls with force on the brake pedal, or the relative resting position of the brake pedal has changed. In these cases it is recommended to inspect the hoses leading to the brake booster as well as the brake booster itself. If the brake booster is in fact faulty it is highly recommended to replace it as soon as possible.

• Hard pedal with no braking power
• Longer stopping distance
• Engine stalls with brakes applied
• Brake pedal position higher than normal

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
