FOR IMMEDIATE RELEASE

               MONRO MUFFLER BRAKE, INC. PROVIDES BUSINESS UPDATE
                    ~ ANTICIPATES 2004 EPS OF $1.17 - $1.19 ~
                 ~ FORECASTS RECORD 2005 EPS OF $1.40 - $1.50 ~

      ROCHESTER, N.Y. - APRIL 20, 2004 - MONRO MUFFLER BRAKE, INC. (NASDAQ:
MNRO) today provided a business update for fiscal 2004, which ended on March 27,
2004, and its financial outlook for fiscal 2005.

FISCAL 2004

      The Company currently anticipates fourth quarter diluted earnings per
share to be between $0.15 and $0.16, which is within the Company's previously
announced range of $0.14 to $0.17. Full year diluted earnings per share are
expected to be $1.17 to $1.19, which represents an increase of over 20% versus
last year's diluted earnings per share of $0.97 (as adjusted for the October
2003 three-for-two stock split). The Company also currently expects comparable
store sales for the quarter to increase approximately 2% versus 7.3% in the
fourth quarter last year, and annual comparable stores sales to increase
approximately 4.7% compared to 2.9% in fiscal 2003.

                                    - more -

      Robert G. Gross, President and Chief Executive Officer of Monro,
commented, "Throughout fiscal 2004, we continued to increase same store traffic
and improve comparable store sales, which helped us to achieve the financial
goals we set at the beginning of the year. As previously announced, we closed
our Mr. Tire acquisition a month earlier than anticipated on March 1, 2004, and
are excited that we will benefit fully from Mr. Tire during its seasonally
strong period. Overall, we are pleased with our performance and confident in our
superior business model, dedicated employees, and industry-leading customer
service that has earned us the loyalty and trust of our customers."

FISCAL 2005 OUTLOOK

      Given positive industry conditions and strong sales trends month-to-date,
the Company's comparable stores sales for April are expected to increase between
3% and 4%. The Company expects fiscal 2005 annual sales of $345 million to $355
million, with comparable store sales growth of 3% to 5%. This translates into
record earnings per diluted share in the range of $1.40 to $1.50, based upon
weighted average shares outstanding of approximately 14.8 million, reflecting a
strong 20% to 30% increase over the Company's estimated results for fiscal 2004.
For the first quarter, the Company anticipates earnings per diluted share to be
between $0.48 and $0.52. Finally, the Company plans to open 25 new stores in
fiscal 2005, of which 20 are projected to be BJ's Wholesale Club locations.

      Mr. Gross concluded, "Our tire, commercial and miscellaneous service
businesses continue to provide opportunities to increase sales and we are
working to grow consumer awareness of our competitively priced, high quality
automotive repair products and services. In addition, while acquisitions are not
reflected in our earnings projections for fiscal 2005, we continue to evaluate
appropriate strategic opportunities for the future growth and expansion of the
business."

      The Company plans to release its full fourth quarter and fiscal 2004
results on May 20, 2004, upon completion of its annual audit.

      The Company will host a conference call and webcast today at 11:00 a.m.,
Eastern Time to provide more details on the Company's Fiscal 2005 financial
projections. To access the call,
