A hole in the Vacuum Hose of a Vehicle Provides Lower Differences in Brake Measurements by the Ministry of Transport Brake Testers Rather Than the Characteristics of the Tester Used.

Carolina Senabre, Sergio Valero, Emilio Velasco


In this research it is studied how vary brake measurement of a vehicle at Ministry of transport facilities when there is a hole in the vacuum hose of the brake booster. Data of brake with the brake boosting system in bad conditions is compared with results of brake of the same repaired vehicle tested on three different roller bed testers from the Maha brand.  Finally, the Efficiency of passing the test with and without the hole in the vacuum hose is calculated to see differences.
