Sick of your severely under-powered factory drum brakes? Sick of them becoming almost non-existent after going through mud or water?

Well look no further!

BBG bring to you a precision CNC milled, BILLET stainless steel brake caliper adapter bracket to suit your Toyota! 

100% Australian Made! It will never rust and you don't need to waste time painting them.

These brakes are seriously tough! They are the biggest, cheapest, easiest and the best on the market. You will not be disappointed.

Current supported models:

  • Most Hilux 4WD models from 1980's til 2015 (Will fit an n70, can't confirm later models)
  • Surf & 4runner


HOWEVER; If you run a 15x8 -22 or a 15x10 -44 offset these will clear IF you slightly clearance one edge of the caliper (as seen in image below).

If you have wheels with even more neg offset, they may bolt straight on with no clearancing.

The tight dimension (no clearance) is 190mm from centre of hub to proudest point on caliper. So an inner rim diameter of 385mm is ideal.


1: REAR HUB FLANGE BOLT CENTRES - These will fit a vast variety of 4wd Toyota vehicles. If you're unsure, you can firstly check your distance between the 2 studs on your backing plate flange. You need a dimension from centre to centre (or over one stud, into another) of 88mm

If required, BBG can 3d print or email you a to scale model to print on paper to check.

2: FOR N70 OWNERS  - Mid way through the N70 generation, Toyota has slightly changed the rear axle. In doing so, this gives roughly a 10mm wider offset from the wheel hub to the backing plate flange where the bracket mounts - Due to bigger wheel bearings. Don't stress though, BBG have an adapter that will be supplied to accomodate this change. BUT we need to know if you require this or not.  


Head around to the inner side of your rear wheel, with a ruler, simply measure from the backing plate to the face that the nut tightens onto. 

If you have roughly 17mm, you need to purchase the "standard" option

If you have roughly 26mm, you need to purchase the "offset" option

What about my handbrake?

Ok, so BBG have been working on developing a solid, reliable and affordable kit for a little while now. BBG started with trying to use the ever increasingly hard to obtain Subaru L series calipers with built in handbrake - but just could not get the handbrake to work to a point where they were satisfied (let alone for customers when selling a kit).  So in conjunction to developing the rear disc brackets, BBG have also developed a transfer case handbrake kit for quite a few models of Hilux etc now. They are far superior to any conventional individual wheel drum handbrake system and is for sale on the website also.

What you get:

  • 2 x Billet brake caliper brackets
  • 4 x High tensile zinc plated caliper mounting bolts & spring washers
  • 2 x Brake banjo bolts (m10x1) & 4x Copper washers

What you also need (LINKS BELOW):

  • Nissan GQ/Y60 Front calipers (single piston) (88-99)    $182.00 (NEW)
  • Nissan GQ/Y60 Front brake pads to suit above caliper   $20.00 (NEW)
  • Nissan GQ/GU/Y60 Rear rotors (315x16mm)                    $74.00 (NEW)
  • Nissan GQ/Y60 Front brake lines (preferably braided)    $53.00 (NEW)
  • Brake pad anti-rattle clips (if using new calipers)           $20-40 (NEW)

                                                                                                   TOTAL: ±$350.00

Also depending on what model car you have you will need a 1" bore master cylinder. An 80 series or 120 Prado series master works in most applications.  BBG have been told by others that the rear discs work fine with the factory LN130 Master cylinder - though BBG changed to an 80 series master and booster anyway and the brake pedal feel is a lot better than the factory master and booster. So, this is up to you, but if in doubt its definitely worth upgrading and is quite an easy job.
