The Owner's Manual iGuide explains how to disable automatic operation of the Electric Parking Brake thusly: "To prevent automatic operation, when the vehicle is stationary, pull out and hold the EPB switch. Within 5 seconds, switch off the vehicle’s electrical system and continue to hold the EPB switch for a further 2 seconds." 😊

Disco5 calipers, 18” Evo Corse wheels from Street Track Life and life is good 😊

I have a set of 18’s just waiting for someone to come up with a solution to this. I do think that the caliper and wheel should have a fair amount of clearance to avoid any damage from rocks. Please Simon don’t give up, try to find a solution for this WITHOUT spacers. Thank you for always trying to help us poor souls in the States.

I even had this problem when I wanted to put the JLR 18" steels on my D240. The front pistons were the 6 pot Brembos! Opted for 20", and sold the steels to some very lucky entrepreneur.

I changed the brakes when I got my D3 for the larger discs thanks to your videos and needed new calliper carriers so also went for 19” wheels. So went up in size though I don’t plan on going off road. So many thanks for those older brake videos 👍

In America we don’t have diesels but we do have P300, P400 and V8. Lots of P400 owners look into the brake swap to be able to fit 18” wheels. My P300 came with 18” steelies.

What a brilliant video, thank you.

Simon…brave work best left to the overseas markets I think! I would just buy 19” and be happy with them rather than stripping the brakes. It clearly is a big job when an overhaul comes up so as my DS was still on its factory build discs as pads at 43,700, I shall continue gently and sell the L494 before it gets past 35,000!!…the JLR brake service bill might be worrying!!😱😱😬😬😀😀😀😀😀

In my opinion you need plenty of gap between the wheel and the calliper in case you bash and flat spot a wheel by accident out on the trail. What is that gap on those defenders that can from factory fit 18s such as your Stig? Could you measure it on the Stig? That is the gap that imo you should be aiming to achieve on the p400 too.

I put cling film over the header tank, and a plain cap. Limits the fluid draining out

Nice video. I have a P400 D90. I had my calipers swapped by a local swap. Your video covers a number of areas that had me concerned. I’m running the TuffAnt Kakadus, +29 offset. The stock 19” wheels, Newsom style 6010 have a +41.5 offset.

Good video Simon 👏👏👍👍👍

I tried this about a year ago and did not like the fitment, too close for comfort. I stuck with 20” wheels. I got some 25mm spacers and with a little trimming on the lower front bumper, removing an aluminum bracket and metal plate on the back side of the wheel well, and a 1.5” lift, I was able to fit a 34.2” very aggressive Toyo Open Country RT Trail (275/65/R20) and still keep the classic mudflaps in place in the front and rear. Any larger and you would definitely need to do more serious trimming and modifications. I did NOT have to relocate the auxiliary radiators in front of the tires with this set up. I did have trim the shroud for the radiators though. It takes a little geometry on figuring out the fitment based on the specific wheel setup you choose but that’s what worked for me and the stance on my D90 looks very aggressive and much larger when parked next to a base model.

Hey Simon. The steelies require spacers and a grind of the swapped Disco5 caliper if they are to fit. Even then it's a squeaker, especially on the fronts. Too close for comfort. The 18" wheels that work have a smaller offset than the OEM +41.5.mm Tuffant Simpson, Tuffant, Kimberley, Redbourne Alston (black Rhino now) and Dakar Zero all work with the swap. Offsets are 27,29,? and 25 respectively. I run my P400 on the OEM factory calipers with Tuffant 18" rims. (Kimberley). A very simple job to grind off the extra metal that seems to serve as a mud scraper. The OEM caliper was designed it seems to clear the 19" wheel of debris. Also you have to remove the mud scraper from the front assembly. 30 second job. 1x Torx t30. i have about 35,000miles on the vehicle since the caliper trim.

Boom Boom!! 💥 💥

Hi Simon…….yet another excellent video if not a little confusing….. Re the Australian reference….. I don’t know if you realise that I’m a Kiwi living on the Sunshine Coast in Queenzland Australia….. and have been since august 2005….. But I refuse to take out Australian citizenship….. yes something to do with yachting…. Americas cup….rugby union….. mota car racing etc etc…… But the biggest reason that I don’t want Australian citizenship is…… I don’t want to lower my IQ to comply!!! Aussies are quite thick…. In my opinion!!!! Regards Ian 👨‍🎤🇳🇿😎👍🍸🍸

Also. Activate service mode opens some valves in the ABS system allows you to bleed the entire system. Simple to do. I've done it at 21,000 and 42,000 miles. A catch vessel 50mm+ above the bleeder valve is best.

Great video as always Simon! I think most people seem to go for the TuffAnt wheel as you say - maybe the Bowler ones could fit too?? PS. Any chance you could investigate what options us V8 (same set up in the p400e too) owners have? Is it just 20” or bigger? How about 19”?

Have you thought of what your insurance company would say if you were involved in an accident and they found you had changed the brakes from standard?
