2014 GS300h DIY brake pads and discs

[Lexus-IS]

Is there any guides out there on how to change the discs and pads for the gs300h? I've changed pads on my IS250 many times but this car is hybrid and has the regenerative brakes so I don't know what is different. 

Are the brake pads and discs also different? Eurocarparts do not seem to sell discs for it only pads.

Regenerative breaking has nothing in common with brakes :) at least with pads and discs bit.

At the back you got standard 1 piston calliper with parking brake in drum while on front you got 4 piston type.  I haven't changed Tham but my plan to give them so nice clean when spring with eventually come.

So is the pad and disc change pretty much the same as other Lexus non hybrid versions? Where does the energy from braking go from? 

Is there anything different on pad and disc change for hybrid versions? What's the process of pressing back the piston on the hybrids? Normal ones you just open the brake reservoir and with a old brake pad and clamp just push it all the way back. 

I read somewhere about keeping keys far away . What's that about?

Brakes are a conventional setup for changing Discs and Pads.. The only difference is that the brake system has an accumulator so when it comes to BLEEDING then you will require Techstream to do so. So unless you are going to change the fluid just go ahead and change as per normal. Nowt different there.

Pads and discs

Euros dont stock.. However German sites like Autodoc, buycarparts.co.uk etc have a wider selection. Nothing special about them its just the rarity/application - Discs however are sided due to the vents (front anyway)

You did ask about the key - are you referring to thieves with scanners and they can 'grab' the code off your transmitting key and open/start your car with that information via some specialist moody tools they have.. Store the keys in a foil lined box so that the transmitting signal is blocked.

Regenerative braking acts through e-CVT,  till you read the gauge in "charge" zone  brakes don't work, and this is the reason why pads last far more.

Maybe but if I remember correctly it was something about even if the car is off the brakes can end up operating if key is nearby.

I found some brembo pads on eurocarparts they have good discount running today. 

Lexus said my front discs were lipped because of worn pads. Does that mean discs need changing or is it just a recommendation?

That's great to hear thanks. So seeing as I'm not changing fluid and don't need to bleed it, I can change it just like a non hybrid Lexus? What about pushing the piston back and leaving the brake fluid cap off? Is that ok on the hybrids? Will it not effect the accomulator or anything?

Yes, yes, and no. Just treat as normal.

I would say why not for the discs I bought a pair from ze germans for about 110 delivered.. as they are 334mm they are REALLY heavy.. about 22kg for the pair. Lexarse charges I think 80 quid each...

For an IS350 BUT they have identical caliper/disc/pad combo..
