CUSIP No.114340102


      This  Amendment  No. 7 to  Schedule  13D  (this  "Amendment")  amends  the
below-indicated  items from the Schedule 13D previously filed by or on behalf of
the undersigned  parties (the "Reporting  Person"),  as previously  amended (the
"Schedule 13D"), by supplementing such Items with the information below:

Item 2.  Identity and Background.

      The Reporting  Persons now include The D3 Family  Canadian  Fund,  L.P., a
Washington  State  limited  partnership  ("D3  Family  Canadian  Fund") of which
Nierenberg  Investment  Management  Company,  Inc., a Reporting  Person,  is the
general partner.

Item 3.  Source and Amount of Funds or Other Consideration.

      The total amount of the funds used to make the purchases  reported in Item
5 was  $1,491,795 and the source of funds for purchases of Shares by each of the
D3 Funds  (including D3 Family  Canadian  Fund),  is the working  capital of the
applicable Fund.

Item 4.  Purpose of Transaction.

We  are  calling  upon  Brooks  to  commit  to an  immediate  10  million  share
repurchase.  Our request is made in a letter to  CEO-elect  Robert  Lepofsky and
Board Chair Joseph R. Martin. This letter is attached to this filing.

The statements by the Reporting Persons in the above-referenced letter regarding
their  investment  in BRKS  represent  solely their own analyses and  judgments,
based on  publicly-available  information  and  their  own  internal  evaluation
thereof.  Those  statements  are not  intended,  and should not be relied on, as
investment advice to any other investor or prospective  investor.  To the extent
those  statements  reflect  assessments of possible future  developments,  those
assessments  are inherently  subject to the  uncertainties  associated  with all
assessments of future events;  actual  developments  may materially  differ as a
result  of  circumstances  affecting  BRKS  and/or  extrinsic  factors  such  as
developments  in the  company's  industry  and  the  economic  environment.  The
Reporting Persons reserve the right to change their internal  evaluation of this
investment in the future,  as well as to increase or decrease  their  investment
depending on their  evaluation,  and to discuss the company and their investment
in it with the  directors  and  executive  officers  of the  company  and  third
parties,  without  further  amending  the  Schedule  13D except as  required  by
applicable rules.

                                       8
