When a caliper on the Bmw 428i Gran Coupe seizes, leaks, or drags, the damage does not stop at the caliper. A partially seized caliper on your 428i Gran Coupe keeps the brake pad in continuous contact with the rotor, wearing the pad unevenly and scoring the rotor surface. By the time the caliper on the Bmw 428i Gran Coupe is identified as the fault, the pads are typically worn asymmetrically and the rotor is damaged. A caliper kit from GeoBrakes addresses every compromised component on your Bmw 428i Gran Coupe together.
The kit for your Bmw 428i Gran Coupe includes the disc brake caliper at the correct left or right hand specification for the 428i Gran Coupe, either new OEM-spec or quality remanufactured to the Bmw 428i Gran Coupe piston dimension and hydraulic pressure rating, brake pads in ceramic or semi-metallic formulation matched to the 428i Gran Coupe caliper and rotor specification, caliper hardware with slide pins, pin boots, and anti-rattle clips for correct caliper float on the Bmw 428i Gran Coupe, brake lubricant for correct pin and shim installation on your 428i Gran Coupe, and copper washers or banjo bolt seals for the brake hose connection where required by the Bmw 428i Gran Coupe application.
A caliper kit is the right call for the Bmw 428i Gran Coupe in three specific situations. After a seized or dragging caliper, because the pads and often the rotor on your 428i Gran Coupe are already compromised. During a high-mileage 428i Gran Coupe overhaul at 150,000 kilometres or more, because caliper piston seals and guide pin boots on the Bmw 428i Gran Coupe are typically at or beyond their service life. After a brake fluid leak at the caliper, because fluid contamination of the 428i Gran Coupe brake pad renders the friction material permanently ineffective on your Bmw 428i Gran Coupe.
New OEM-specification calipers for the Bmw 428i Gran Coupe are manufactured from fresh materials with no prior service history, the strongest choice for 428i Gran Coupe vehicles in high-corrosion environments. Remanufactured calipers use original Bmw 428i Gran Coupe housings rebuilt with new pistons, seals, and boots, performing identically to new units at a lower price point for most 428i Gran Coupe replacement applications.
Calipers for the Bmw 428i Gran Coupe are the most position-specific brake component in the catalogue. Left and right calipers for the 428i Gran Coupe are not interchangeable. Our vehicle selector confirms the correct caliper kit for the Bmw 428i Gran Coupe exact year, axle position, and left or right side before purchase.
Should I replace both calipers on my Bmw 428i Gran Coupe at the same time?
It is strongly recommended. If one caliper on the Bmw 428i Gran Coupe has seized or leaked, the caliper on the opposite side has experienced the same conditions and age on your 428i Gran Coupe. Replacing both restores balanced, even braking and eliminates the risk of the second 428i Gran Coupe caliper failing shortly after the first is replaced.
Do I need to bleed the brakes on my Bmw 428i Gran Coupe after installing a caliper kit?
Yes. Opening the hydraulic circuit on the Bmw 428i Gran Coupe to install the new caliper allows air to enter. After installation, the brake circuit on the 428i Gran Coupe must be bled at the caliper bleeder screw to purge all air and restore a firm, consistent brake pedal on your Bmw 428i Gran Coupe.
What is the difference between a new and remanufactured caliper in the Bmw 428i Gran Coupe kit?
A new caliper for the Bmw 428i Gran Coupe has no prior service history and is the stronger choice for high-corrosion environments. A remanufactured caliper uses an original 428i Gran Coupe housing rebuilt with new pistons, seals, and boots, performing identically to new at a lower price point for most Bmw 428i Gran Coupe applications.
