View Full Version : L494 Brembo 6 piston calipers on my Discovery 4

After experiencing some brake flutter on my Discovery 4 I decided to look into brake upgrades for my 2013 Discovery 4.
I had already upgraded the discs to a T2 DBA slotted, DBA Street Performance pads and completed a brake fluid flush with Penrite DOT 5.1 (often over looked when people have issues with brakes.)
After doing some research I found a video from 6 years ago from Powerful UK and some Google searches provided me with some companies in the UK advertising the upgrade.
I sourced a set of L494 Brembo 6 Pistons here out of Melbourne and brought new disks and pads via Supercheap (part numbers provided in the pictures attached.)
Everything is bolt on, being able to use the dust shields that come standard with the 365mm TRW setup.
The 380mm DBA slotted T3 rotors had no clearance issues and the calipers bolted on like they were meant to be there.
I'm currently 80ks into the wear in process of 200kms and to be honest the difference is night and day. The Disco is running Continental Contact Sports, so a full road tyre and so far the ABS has pulled the Disco up fine with the Brembos. Both my daughter and I were very impressed, as she helped me with the conversion.
At $500 each for the calipers and some man maths, with rotors and pads, brings it to a total of around $1,800 to convert the Discovery 4 into something that can stop on a dime.
I will admit, I thought the factory brake setup, even with the upgrades I've conducted was very good, but this is next level. I'm looking forward to hitting the 200km mark and standing on the brakes to see weather the ABS, Tyres or the Brakes is the weakest link.
If anyone is interested, I'm happy to answer any questions, I'll keep you updated on here once I've finished the wear in process. 19545619545719545819545919546019546119546219546319 5456195457195458195459195460195461195462195463

I will add, you require a 20 inch wheel to have the clearance to fit the Brembos.

D5 19" should also fit as they have less offset than D4/L494/L405/L663 19" rims. I have them on my 2021 L405 but 20" could be a better option depending on what tyres suit one's needs best.

Good afternoon all,

Just thought I'd drop an update on the Brembo 6 piston conversion.
I've completely run them in now and am extremely happy with the outcome.
The brake pedal feel is more confidence inspiring with a nice progressive feel as soon as you start pressing the brake pedal.
I have conducted a few brake tests to ensure there will be no issues and they make short work of pulling up the 2,700kg Discovery, combined with the Continental Conti Sports I'm sure.
I'd be interested to see how they'd perform with a set of AT or an older set of tyres.

Thanks

Scott

I had the pistons and pads resealed/replaced about a month after I got mine as one side was a bit sticky..
5 years and 50k later and I'm still on the same pads, and thats after towing a 3T van around Oz for 18months.

Maybe not the kind of performance you are after though... [tonguewink]
