Ford Transit Hard Brake Pedal & Vacuum Pump Faults
We diagnose and fix hard brake pedal issues caused by tandem vacuum pump failure on Ford 2.0 EcoBlue engines.
Ford Transit Hard Brake Pedal & Vacuum Pump Faults
The Ford 2.0 EcoBlue engine used in Transit and Transit Custom models can suffer from a hard brake pedal. This is often caused by a failure in the tandem vacuum and oil pump assembly, which provides the necessary power assistance for your braking system.
When the vacuum pump fails, the brake pedal feels solid and requires significantly more force to stop the vehicle. In many cases, this failure is linked to debris from a degrading wet belt blocking the oil supply to the pump, leading to mechanical seizure. We provide honest technical assessments to identify if the pump itself has failed or if there are wider issues with the engine's lubrication system.

Frequently Asked Questions
This is typically caused by a failed tandem vacuum pump. On the EcoBlue engine, this pump provides the vacuum needed for brake assistance. Without it, you are relying on pure physical leg strength to stop the van.
No. While the brakes may still function, the effort required to stop is dangerously high and your stopping distance will be much longer. You should have the van recovered to a garage immediately.
Frequently, yes. If the wet belt starts to perish, rubber debris can block the oil feed to the tandem pump, causing it to seize. We always check the oil pickup during this repair.
We usually complete this repair within one working day. This includes the time needed to drop the sump, inspect for debris, and thoroughly test the new pump.
Yes. Because the vacuum pump is also the oil pump (a tandem unit) and is lubricated by engine oil, we always replace the oil and filter to ensure no contaminants damage the new part.
