The average cost to repair a power brake booster is approximately $420 as of 2015, including parts and labor, according to Repair Pal. This price reflects the national average in the consumer market.
The estimate given on Repair Pal combines the lowest national price and highest, although the total price greatly depends on the location of the service. For example, brake booster replacement in some of the least expensive cost-of-living states was approximately $328, while the more expensive states reached as high as $497.
The parts play a larger role in the cost of brake booster repair; however, using online resources to purchase the brake booster is a good way to save on the overall repair cost.
