Bmw 428i Xdrive Disc Brake Caliper in US

The disc brake caliper on the Bmw 428i Xdrive is the hydraulic clamp at the centre of your 428i Xdrive disc brake system. Every time you press the brake pedal on your Bmw 428i Xdrive, brake fluid pressure forces the caliper pistons outward, squeezing the brake pads against the rotor and generating the friction that stops your vehicle. A seized, leaking, or sticking caliper on the 428i Xdrive interferes with that process at the source, causing uneven braking, accelerated pad and rotor wear, and pulling to one side that worsens over time.

Signs of a Failing Disc Brake Caliper on the Bmw 428i Xdrive

• Bmw 428i Xdrive pulls strongly to one side during braking, a seized caliper on one side applies more force
• Brake pedal on your 428i Xdrive feels soft or spongy and improves after pumping, caliper piston seal leaking
• One brake pad on your Bmw 428i Xdrive axle wears significantly faster than its partner
• Brake drag on the Bmw 428i Xdrive, vehicle feels like it is fighting resistance at normal road speed
• Visible brake fluid leaking from the 428i Xdrive caliper body or around the piston boot
• Grinding or scraping from one Bmw 428i Xdrive wheel that persists after confirming pads are not worn

New OEM-Spec vs. Remanufactured Calipers for the Bmw 428i Xdrive

New OEM-Specification Calipers for the Bmw 428i Xdrive

New OEM-specification calipers for the Bmw 428i Xdrive are brand-new units manufactured to the exact piston dimensions, seal specifications, and material tolerances of the original 428i Xdrive factory part. They offer the longest service life on your Bmw 428i Xdrive and are the strongest choice for higher-mileage 428i Xdrive vehicles or those operated in high-corrosion environments.

Remanufactured Calipers for the Bmw 428i Xdrive

Remanufactured calipers for the Bmw 428i Xdrive are original caliper housings completely disassembled, cleaned, inspected, and rebuilt with new pistons, seals, boots, and hardware. Quality remanufactured units perform identically to new calipers for most Bmw 428i Xdrive replacement applications and offer excellent value.

Frequently Asked Questions - Bmw 428i Xdrive Disc Brake Caliper

Should I replace brake calipers on my Bmw 428i Xdrive in pairs?

It is generally recommended to replace calipers as an axle pair on the Bmw 428i Xdrive, both left and right on the same axle, to maintain balanced braking. If one 428i Xdrive caliper has failed, the caliper on the opposite side has experienced the same service conditions and is likely at a similar stage of wear.

How long do disc brake calipers last on a Bmw 428i Xdrive in US?

Bmw 428i Xdrive calipers typically last 100,000 to 150,000 kilometres, but American road salt and moisture accelerate corrosion of 428i Xdrive caliper guide pins, slide pins, and piston seal boots, often causing premature failure on the Bmw 428i Xdrive well before that figure.

Can a sticking caliper on my Bmw 428i Xdrive damage my brake pads and rotors?

Yes. A 428i Xdrive caliper that does not fully retract keeps the brake pad in partial contact with the rotor between stops, generating constant friction and heat on your Bmw 428i Xdrive. This rapidly wears both the pad and rotor surface on your 428i Xdrive and generates enough heat buildup to damage adjacent components over time.
