If your brake pressure 1 and/or 2 warning lights are on, or they flash when you touch the brakes, they need urgent changing. You can also conduct a safety test as follows; Run the car for 5 minutes, turn the engine off, then turn the ignition to the “on” position without starting the engine. Start pushing the brake pedal and count each depression. If anyone of the two Brake Pressure lights come on in less than 10 counts, then you should change them.

There are 2 accumulators per car and the price is for 1 unit.

* NOTE: These look a little like the rear gas spheres but are not the same part and as such NOT interchangeable
