GiroDisc 14-20 BMW M2/M3/M4 (F8X w/Blue Calipers) 380mm Front Dust Boot

GiroDisc caliper dust boots for the 14-20 BMW M2/M3/M4 (F8X w/Blue Calipers) 380mm, front caliper. Replacement piston dust boots keep dirt, water and brake dust out of the piston bores — the usual cause of sticking pistons and uneven pad wear.

Notes

• Each set covers one caliper. Order two for a complete axle.
• Boots only. If the caliper is also weeping fluid, use the matching caliper rebuild kit, which includes piston seals.

Fitment

• Vehicle: BMW M2 (F87), BMW M3 (F80), BMW M4 (F82)
• Axle: Front
• Manufacturer part number: CDB1-186

Important fitment notes
