PDI Upgraded Brake Booster suitable for 105 Series Landcruiser

Braking upgrades should be done in conjunction with engine conversions and power increases – PDI brake boosters will give a 50% increase in booster ratio over the standard brake booster. In fact any other changes would be minor compared to our booster upgrade, unless you are replacing damaged or non-functioning systems.

Our PDI dual diaphragm brake boosters have been ADR tested and proved to pass all tests. Our design allows us to exceed the standard brake specifications for those with increased weight and larger tyre diameter

NON-ABS Model only

Double Diaphragm Design
By changing to a double diaphragm booster the effective push on the pedal has decreased by 80kg under heavy braking. By increasing the diameter, which has made the whole unit larger and increased the effect to 180kg. Considering it is likely the normal push would be under 50kg for full braking, this is a significant improvement that will be noticed.

Does it make a difference?
The brake booster upgrade makes a noticeable difference, and we are sure every cruiser owner would install after driving a cruiser fitted with one of these boosters.

Brake Lines
We recommend these be installed with braided brake lines as line pressure will be increased and the standard lines may be compromised if still original. This is both due to age and the potential for damage as they are fitted to a 4WD. Installing braided lines will also give a better result as factory flexible lines bulge and reduce effective application of the pedal.
