Iruna Vacuum Pump
All power assisted brakes are dependant on a vacuum which, in petrol powered vehicles, is usually derived from the engine. Should the engine stall and cut out, you will only have the use of any vacuum left in the power brake booster. An alternator driven pump on a diesel engine, as is used on most 4×4 vehicles, and the same situation will apply. See our Technical Training pages for more details.
More and more brake applications are used on off-road and mountainous driving. Loss of vacuum is found to be faster than normal. Fit the Iruna vacuum pump and and be sure of having a vacuum available when needed. For peace of mind this is a MUST if towing a trailer or caravan.
