I have a problem and that's the brakes fade very quickly when used quite hard use, I run 302's with volvo pads and recently renewed DOT 4. I think the main contributing factor to this is that I don't have a turbo heat shield, Id prefer not to have one for easier access to it so instead have considered a blanket. Does anyone have any experience of them?

Thanks.

In opinion the problem is not heat coming off the turbo but it due to the crap brakes.

Ferrodo ds2500's.
I battered mine once bedded in & never had fade with 5.1 fluid.
I will be investing in some once the plod pads are past it.

Dot 4?

I believe Volvo spec is dot 4.1 (although there's probably not much difference). If you're a bit heavy on the brakes, it'll be best to upgrade to dot 5.1 and braided hoses (about £50 from fleabay), at least the fluid will last longer.

The heat from the turbo is more likely to have an affect on the master cylinder than the brakes themselves I would think.

The 302, are just not good enough, I've tried every type of pad before on 302s always using braided lines and flushing brake fluid, before resulting into changing calipers and discs for larger.

Including grooved and drilled discs

In fact I was getting more braking from the rears on my t5r saloon, using cheapo pads, than 302s with new-ish calipers on Volvo pads.

This was going on information provided by the brake rollers at an mot station as my neighbour is an inspector and fellow t5 owner.

The heat from my turbo would get hot enough to melt the plastic elbow into the brake servo, it never caused brake fade though, but if stuck in traffic it would boil the fluid and I'd end up with no clutch. so I would say your brake fade is due to the dot 4.1

The heat also damages the vacuum etc hoses that run above the heat.I had to change a main vacuum pipe on an 850 as it got hard and started cracking.

Claymore how did you sort it as I start to lose clutch pressure and get really bad break fade when been running a while sorry for jumping in

They seem like a bad idea to me, surely it'll cook the turbo?

As long as the cold side isn't wrapped. You see plenty of tuned ricers with the manifold, turbo, downpipe etc wrapped these days.

Just put the heat protection of some kind on the pipes above and replace them if they are not flexible,u will be just fine,no need for anything on the turbo.Or you can make up a quick removable heat shield.

Why do you need constant access to the turbo? You problem would be solved easily by just refitting the heat shield. There not that difficult to get on and off, especially with new bolts.

They r a lot more pain than P2 models to refit.P2 is actually a piece of cake
