The Meritor brake booster R43MDC4056X is a genuine OEM brake system component for heavy-duty truck applications. Brake boosters amplify pedal input to deliver consistent stopping force across the air or hydraulic brake circuit, making correct part identification critical before ordering. If you are cross-referencing from an older Rockwell part number or need to verify this booster fits your specific axle and brake configuration, call us before placing your order.
