VDJ79/78/76 HDJ79/78 HZJ79/78 Series Landcruiser PDI Dual Diaphragm Upgraded Brake Booster

Braking upgrades should be done in conjunction with power increases and we have found the biggest improvement can be achieved with this mod and PDI brake boosters will give a 50% increase in booster ratio over a VDJ79 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 (both GVM and GCM).

• larger wheel diameter
