PDI Upgraded Brake Booster suitable for 80 Series Landcruiser

PDI Upgraded Brake Booster suitable for 80 Series Landcruiser

Braking upgrades should be done in conjunction with engine conversions and power increases – A PDI dual diaphragm brake booster for the 80 series is not only new but is larger and will give an increase in brake performance as the booster assist ratio is higher than factory. 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

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.

Fitment:
These are suitable for installation on both the petrol and diesel models, with and without ABS. It is likely this is going to be the first time you have felt the ABS unit function on the bitumen. For those fitting to petrol models we suggest and additional vacuum reservoir be added to ensure the booster is able to provide full assist for a period after the engine is turned off or if being driven enthusiastically where vacuum build up is limited.
The only fitting issue is for those with rear air con or ice box console where the alloy pressure lines are routed close to the brake booster and will result in interference such that our larger boosters can’t be fitted.
