Replacement Parts:


Engine brakes are an essential part of diesel engine operation, providing a major role in retarding the engine on down slopes and during regular stopping. Consequently, they save substantial wear on your service brakes and ultimately money in your wallet.

Engine brakes are used regularly and their moving parts wear over use and time. It’s not unusual to see a 20-25% decline in engine retarding with normal wear over 300,000 miles. When your engine is scheduled for regular maintenance such as injector change or valve set, the first item to be removed in the process is the engine brake. It makes logical sense from a cost-of-labor stand point to perform engine brake maintenance at this point in time.

Pacbrake’s Tune-Up Kits to restore your maximum engine brake performance with all the parts you need in one convenient package, no matter what brand of engine brake you have:
As a driver, you may not notice the declining engine brake efficiency as the loss is gradual. With the decline in your engine brake efficiency comes more regular use and wear of your service brakes. A single brake reline will cost you many times more than an engine brake tune up kit. In the long run, failing to maintain the engine brake efficiency will cost you more in brake relines. Make safety a priority while saving time and money.
