GSF EBC Brake Pads

[hockeyedwards]

EBC list front pads DP21867 as compatible for the GSF as well as others, anyone used these or have any other recommendations for pads? Seeing the other threads am definitely not getting Lexus to do them for such a ridiculous price!

[ColinBarber]

Not sure Greenstuff are up to the job, too much weight and power. Red or Yellow should be more suitable, no idea how well they work on an F though.

[hockeyedwards]

Thanks for the tip, might take a plunge on the Red or Yellow then! There is mention of replacement sensor wires... any ideas if it is a 'must' to replace them as well?

[B1RMA]

How much are the Lexus pads then?

[Twellsie]

I have tried EBC a few times over the years, green, yellow and blue and have never been happy, do Euro car parts not do Btrmbo pads for the GSF?

[NemesisUK]

Never been comfortable with second-guessing the engineers regarding braking systems.

Unless I was tracking the car, or had significantly increased performance I would stick with OE pads. Cost is part of ownership...

I have tracked my ISF on yellowstuff pads and cannot speak highly enough of them.

About to track it next month on Ferodo DS2500's (to be fitted next week) I will make a comparison after that.

£393 to £491 depending on the dealer. LexusPartsDirect quoted the £393.

The sensor wire is a loop of wire that goes against the pad. When the pad wears down the wires is also worn away, becomes open circuit, and triggers the warning light. If your pads are worn to the point of illuminating the warning light then the sensor is damaged and needs to be replaced.

If you are replacing pads early then the existing sensors can be reused - this is providing a different design isn't required because of different pad manufacturer - which I doubt as they would just use the OEM pads as a design template.

Or you can just forget about the sensor wires and short out the circuit at the connector and waterproof to stop the warning light coming on.

In all honesty these cars cost b*gger all to maintain properly so I don't think I'd bother going elsewhere. I admit that some aftermarket parts are better than originals and some are better suited to specific tasks but for everyday road use I'll stick to OEM.

Try running a V12 twin turbo AMG they eat front pads and discs too, I was quoted £2800 from Brooklands Mercedes for them that was the proper AMG items.

[hockeyedwards]

Makes sense, thanks for the info. Last MOT quoted me having around 4mm of pad left, so I'm safe with the sensor if I replace soon, which I intend to do. Probs gonna give EBC a bash and see how it turns out.. what could possible go wrong haha!

How many miles have you recorded on them?

[B1RMA]

I've just done a bit of searching on the USA based forum and it appears Nengun distribute Endless MX72 pads for both the RCF and GSF. There are some mixed reports but it looks like very little brake dust. They are a bout £200+

[hondansxr]

i have these available with a set of yellow stuff pads they were for an isf  dont know if there the same as gsf

Personally 16k, but the car has done just shy of 30k in total

Thanks good to know, reading through some of the threads on the USA forum it would appear that the pad material is so hard it's the discs that wear and created the dust. I'm no expert so don't know how factual this is

Car goes up in the air tomorrow for the wheels off clean, so I can inspect the discs better. Might take some pics if I find anything of interest.

If you have a micrometer handy It'll be interesting to see what thickness remains on the discs. I did have some figures of the original thickness listed on the USA website somewhere.

Don't have one, but I know a few local people that might, it would be interesting to see the thickness change!

[B1RMA]

 

Here are the figures hopefully someone who knows about these things can confirm if this is correct. I did take it straight from the USA forum.

 

Front brake pads Standard Thickness: 9.75 mm (0.384 in.)

Minimum Thickness: 1.0 mm (0.0394 in.)

Front rotors Standard Thickness: 34.0 mm (1.339 in.)

Minimum Thickness: 31.0 mm (1.220 in.)

Rear brake pads Standard Thickness: 11.68 mm (0.460 in.)

Minimum Thickness: 1.0 mm (0.0394 in.)

Rear rotors Standard Thickness: 28.0 mm (1.102 in.)

Minimum Thickness: 26.0 mm (1.024 in.)

[ColinBarber]

^ those are correct. Minimum for pads is 1mm, discs are 31mm front and 26mm back - this is actually stamped on the rotor.

I also read that if you run the pads too low you need to replace the sender which I guess makes sense if they are damaged by the disc.

Yes that is how they work. You wear away the wire, breaking the circuit and illuminating the warning light.

Got it now, you did state this earlier and I din't take that in, got there in the end.
