Abstract
In order to allow a single operator on a vehicle assembly line to attach a brake servo to a bulkhead by moving round from the engine compartment side to the passenger compartment side, a brake servo is fitted with an adhesive and insulating seal (14). This seal has two adhesive faces and each of the two adhesive faces has a protective film provided with a tab (15, 16); each protective film is of a distinctive color. One of the two protective films has cuts (17) along holes (10) in the seal, these cuts being intended to make it easier for the protective film to be removed as the brake servo is mounted against the bulkhead.

A brake servo (4) to be fixed in an engine compartment (2) against a bulkhead (3) and screw-fastened from a passenger compartment (1) side of a vehicle, comprising an adhesive seal (14), characterized in that the seal (14) has a protective film with tabs (15) and (16) corresponding to each adhesive face of the seal (14), and in that the protective film to be stuck to the bulkhead is precut (17) along lines leading from stud holes to an outer edge of the seal (14).
A method of mounting a brake servo on a bulkhead from an engine compartment side of a vehicle, characterized in that the method comprises the following steps:
- applying an adhesive seal to the brake servo on a face of the brake servo that includes a pedal box control rod (9),
- applying the brake servo fitted with the adhesive seal from the engine compartment side against an aperture (11) in the bulkhead that corresponds to a hole through which the control rod associated with a control pedal box passes,
- supporting, with the adhesive seal, the brake servo on the bulkhead, and
- tightening nuts (18) that attach to studs (8) of the brake servo from the passenger compartment side.
