FL S8 discs & pads NLA at TPS?

[RICKY D]

The brakes squeak horribly on my Dolphin s8 so I asked my pal to order me new front & rear discs and pads from TPS. He said they laughed and said these have been NLA for ages.

He ordered me brand new ones from TPS about 4 years ago on my Green beast so I didn’t expect any issues this time round. I always buy OE brakes where possible because I can’t deal with squeaky brakes but it looks like I will need to try an alternative this time round.

This thread is the most recent one I found by the Laird.

Would you say this is the best route? How have they faired since being fitted? Any squeaky shenanigans?

Febi discs & TRW pads are currently the most satisfactory combination I've found.

For the brake discs I find that cheap discs are usually made out of steel instead of cast iron. I am not talking about the process of making them as steel discs are still made by casting and then machining but about classification where iron with less than 2% carbon is called steel and cast iron is over 2% carbon.

Simple cast iron is cheap to make but extra carbon make it brittle and not suitable for brake discs, to make stronger cast iron more advanced , more expensive manufacturing techniques and additives are needed so many cheap manufacturers just choose steel. Cast iron has better thermal properties, better corrosion resistance and is less likely to squeak. It also wears slower so cast iron discs last longer. On the other hand steel is stronger and has lower density, discs can be made thinner reducing weight or you can let the wear thinner an still maintain required strength. On the track car it might be beneficial to get steel discs if you can save weight but for everyday driver cast iron is more suitable. The issue is that manufacturers are not very upfront about material or carbon conten. It's also not necessarily easy to tell when you have them in your hand. Easiest indicator is probably when they are on the car when it's raining to compare how quickly and how rusted friction surface gets when parked in rain.

I think I’ll give them a try MJ. The discs I found using your part numbers in the previous post from The Laird, but I can’t seem to find the pads! I think they are out of stock

If you get a chance could you help me find a set please

Interesting. I have noticed that the discs rust up very quickly on these so I think you’re on to something.

I don’t like the way they feel under heavy braking either so I can’t wait to change them.

The brakes on my S8 have never been better since taking MJ’s recommendations for discs and pads. And fitting MJ’s little aluminium brake block by the master cylinder, of course.

[strummagnet]

I think they are the same combination found on mine and have had no issues for the last few thousand miles they have been on the car.

[RICKY D]

Excellent. As soon as I can work out the correct parts I will buy them and get my pal to fit them.

I have the aluminium brake block in place as well…..on both 8’s actually. It made a huge difference on the pedal feel on Dolph. Now it’s the actual brakes themselves that let it down

Brake discs purchased…hopefully the correct ones

I can’t seem to locate the pads. If anyone can help me track down a pair front & rear that would be appreciated.
