SUPERSEDES S.I. 03/83-614
During 1984 production and beginning approximately with VIN Serial Numbers E1024000 and E2011300, a new brake pad retention pin was introduced
which reduces the likelihood of an audible knock or clunk during brake application in reverse. The new pin is identifiable by a new plating color
(yellow) and a new bend which differs from that described in S.I. 03/83-614.
Brake noise is caused by the clearance (see point A) between the brake housing and the caliper. The new pin (P/N 89-90-194) reduces this clearance
thereby eliminating excessive caliper movement.
The new pin may be fitted to any late model 900 which exhibits objectionable brake "clunk" or knocking in reverse.
NOTE! A certain amount of brake housing-to-caliper clearance is necessary to ensure correct alignment and brake function. The new brake retention pin
is not designed or intended to completely eliminate brake housingto-caliper clearance.
