PDI Dual Diaphragm Brake Booster Upgrade suitable for Toyota LandCruiser 70 Series VDJ76 VDJ78 VDJ79 GDJ76 GDJ78 GDJ79

A 70 Series with a canopy, a big tray, bigger tyres or a trailer behind it asks a lot of the factory brake booster. This PDI booster replaces it with a brand new dual diaphragm unit. It’s larger than the factory booster and has a higher assist ratio, so the same push on the pedal puts more force into the master cylinder.

It’s ADR tested and compliant. Pick the ABS or non-ABS version to suit your truck.

Please note: the four cylinder GDJ 70 Series is covered by the ABS version only. The non-ABS version suits the V8 VDJ models.

🚗 Suitable for:

• Toyota LandCruiser 70 Series VDJ76 wagon, 1VD-FTV V8
• Toyota LandCruiser 70 Series VDJ78 troop carrier, 1VD-FTV V8
• Toyota LandCruiser 70 Series VDJ79 ute, 1VD-FTV V8
• Toyota LandCruiser 70 Series GDJ76, GDJ78 and GDJ79, 1GD-FTV four cylinder (ABS version)
• ABS and non-ABS versions available for the VDJ

📦 What’s Included:

• 1 x PDI dual diaphragm brake booster, ABS version (VDJ and GDJ) or non-ABS version (VDJ)

🔧 Fitment Details:

• Order the version that matches your truck. ABS and non-ABS 70 Series need different boosters.
• Suited to trucks running a higher GVM or GCM, larger wheels and tyres, or touring, towing and off road setups.
• With the stronger booster fitted you can set the load proportioning valve (LPV) properly, rather than relying on the LPV rod spacer that many lift kits add.
• We recommend fitting braided brake lines at the same time (2007 to 2016 VDJ braided lines or 2016+ DPF VDJ braided lines). Line pressure goes up with this booster, and old rubber lines swell under pressure, which softens the pedal.

⚙️ Why Choose PDI:

• PDI (Performance Diesel Intercoolers) have been making brake boosters since 2019. They tested the common “30% upgraded” boosters on the market before designing their own.
• Two diaphragms and a larger diameter than the factory booster give it more assist.
• Brand new, not a reconditioned factory unit.
• ADR tested and compliant.

❓ FAQs:

Q: Does it suit the 1GD four cylinder GDJ79?
A: Yes. Order the ABS version. PDI make the ABS booster to suit both the V8 VDJ and the four cylinder GDJ 76, 78 and 79 Series.

Q: How do I know if my 70 Series has ABS?
A: If the ABS warning light comes on with the dash lights when you turn the key, it has ABS. If you’re still not sure, send us your VIN and we’ll check.

Q: Does it suit the HZJ or HDJ 70 Series?
A: No, this one is for the VDJ and GDJ models. The six cylinder HZJ and HDJ 78 and 79 Series have their own PDI booster, and so does the HZJ75.

Q: Do I need braided brake lines as well?
A: They aren’t required, but we recommend them. The booster raises line pressure, and factory rubber lines swell under pressure, which softens the pedal.
