Rear Disc Brake Theory

This has been a long awaited topic amongst all, as we’ve all pondered and wished we had rear disc brakes. Unfortunately, Toyota didn’t see the demand for them in our US market.

I’ve spent countless hours researching and I’ve discovered that Toyota developed parts that use similar bolt patterns for certain parts. So I’ve noticed there’s a pattern on some cars with regards to their rear brakes…thus having the potential to have brakes interchangeable.

I have come to the conclusion that the following two setups will fit the rear of the RAV4.1’s in the US. I’d just like to note, since I’ve sold my RAV4 I can’t confirm these setups with work, it’s truly up to another brave RAV4 owner to give it a go!

The most difficult part of both setups is acquiring the back plate which is how it all comes together. These back plates are expensive from the dealer and can cost upwards of $300. The easiest way to do this is to swing by a local wrecker or junkyard and buy them there…make sure they are complete with the entire brake assembly.

Here’s what you’ll need:

– Backing Plates
– Drum Parking Brake Assemblies
– Drum Brake Pads
– Rotors
– Brake Pads
– Brake Shims
– Brake Calipers
– Brake Calipers Brackets
– Parking Brake Cables (may not need them as stock cable compatibility has not been confirm)

The first setup comes from our beloved family minivan, the Toyota Sienna specific the 3rd generation Sienna. While I unraveled these I discovered this setup is used on the rear of other Toyota and Lexus models:

TOYOTA SIENNA 2011-2015

TOYOTA HIGHLANDER 2014-2015

LEXUS RX350 2010-2015

LEXUS RX450H 2010-2015

Here’s a few photos of the major parts you’ll need with specs.

The second setup comes exclusively from theToyota Rav4.2 or simply the 2nd generation Rav4. These are a bit harder to find do them being a less common option and less of them on the road. Note these setup does not require a brake caliper bracket as it was design to have less parts.
