Approximately 10%

Raises Fiscal Year 2009 Diluted EPS Range to $1.17 to $1.20

ROCHESTER, N.Y., March 24, 2009 (GLOBE NEWSWIRE) -- Monro Muffler Brake, Inc.
(Nasdaq:MNRO), a leading provider of automotive undercar repair and tire
services, today announced that the Company has raised its guidance for fiscal
year 2009. It now anticipates fiscal 2009 sales to range between $475 million to
$477 million, with a comparable store sales increase of approximately 7%. This
compares to the Company's previously anticipated sales range of $467 million to
$471 million and comparable store sales growth range of 5% to 6%. In addition,
the Company now conservatively expects diluted earnings per share for fiscal
year 2009 to be in the range of $1.17 to $1.20, up from its previously
anticipated range of $1.14 to $1.19. This estimate compares to fiscal 2008
earnings per diluted share of $1.00.

For the fourth quarter of fiscal 2009, the Company expects a comparable store
sales increase of approximately 10%. The Company now expects diluted earnings
per share for the fourth quarter of 2009 to be in the range of $0.12 to $0.15,
up from its previously expected range of $0.09 to $0.14. This estimate compares
to $0.10 in the prior year quarter.

Based on current visibility and economic trends, the Company anticipates full
year 2010 comparable store sales growth in the range of 4% to 7% and full year
2010 diluted earnings per share in the range of $1.30 to $1.45. This estimate
includes an expected 100 basis point gross margin improvement related to
declining oil and tire costs.

Robert G. Gross, Chairman and Chief Executive Officer, commented, "We are
pleased that we are able to raise our sales and earnings estimates for the
fourth quarter and fiscal 2009 and deliver our eighth consecutive year of
positive same-store sales growth. Further, we expect to record very strong
monthly comparable store sales increases in all three months of the fourth
quarter, which is especially gratifying given the challenging economy. We also
expect that we will achieve earnings leverage lower than originally anticipated
for the quarter, as we aggressively advertised and promoted tire and maintenance
services in order to opportunistically gain market share from some of our direct
competitors and dealerships. The result is an expected strong 5% increase in
traffic for the quarter which we expect will help us to drive return business
and establish long-term customer relationships."

Mr. Gross continued, "As we move toward the next fiscal year, we remain
cautiously optimistic, despite macro factors, and expect continued positive
momentum and improved operating leverage driven by strong comparable store sales
growth and margin expansion."

The data provided for the fourth quarter and full year fiscal 2009 is based on
preliminary unaudited internal results and is subject to change as the Company
completes the preparation of full consolidated financials statements for the
period. The Company plans to release its fourth quarter and fiscal 2009 results
on May 28, 2009.
