This expander boot is a rubber dust cover fitted to the handbrake or braking system components associated with the LT230 transfer box, LT77S, and LT85 gearbox assemblies. It functions as a protective sleeve, preventing ingress of dirt, moisture, and debris into the adjuster or cable mechanism, which can cause corrosion, binding, or premature wear. Deterioration of this boot is common on older vehicles and typically presents as visible cracking, tearing, or collapse of the rubber. Key Features Rubber expander boot designed to seal and protect the braking system dust cover assembly On Series 2, 2A, and 3 applications, fitment uses a spring clip retention method rather than bolts - confirm correct clip is present before installation Fits vehicles up to chassis number LA935629 on Defender applications - verify chassis number before ordering Inspect adjacent seals, clips, and handbrake cable condition at time of replacement to avoid repeat disassembly Vehicle Fitment Fits Defender (1986–2006) up to chassis LA935629, Discovery 1 (1989–1998) from VIN 28D283204E, Range Rover Classic, and Series 2, 2A, and Series 3 models with later-type spring clip fitment.
