Window Regulator pinion brake spring - all Feltham models including  Lagonda's, these cure the door drop glass lowering by themselves or being pulled down from outside, bit fiddly to fit but we are on the 2nd batch & they stop you needing wedges to stop the glass falling as you drive along or being pulled down from the outside.

Carefully take the door card off,taking care not to lose the handle pegs, take the regulator off the car, bend the 5 tags carefully gently back & ease the pinion & pinion housing off the main body, strip & clean it of all grease, replace the brake spring & check the gear condition, if worn we sell these aswell. Reassemble with a small amount of lithium grease. Refit the cover / pinion into the 5 slots & bend the tags back, Test it on the bench as other swivels may need lubricating. refit to car

Note that we often stock used window regulators in GWO
