B-b-ber BREMBOS!

[ChimpOnGas]

In true PH "Show and Tell" stylee, here are my new four pot Brenbo callipers




A set of plain vented 324mm discs and these callipers gripping them all squeezed under my 16" Imola wheels should make stopping 'Ol Gasbag' from speed an eyeball popping experience

That's more brakes than a 4.5 Lightweight Cerbera!!!! so perhaps they're a bit overkill for 'Ol Gasbag'?

Or are they

[rigga]

Not overkill, they work just fine

That's similar to what I have, Dave. With Hawk racing pads working on grooved ventilated Black Diamond disks. Stops the car from well over 100 mph with confidence every time, and no brake fade.
So are you thinking of joining us for a track day at Hullavington on Friday 11th March?

They won't fit .

Fantastic upgrade. The original 500 bigger brakes from the TVR parts bin are only worthy for the rubbish tip outside the old factory. In fact they should have thrown the lot in there rather than fitting them to the cars!!!!

The AP caliper fits under 16's so why not the brembo, explain yourself sir!!!

Oh but they do

[carsy]

Is this in preparation for going FI ?

[SILICONEKID345HP]

With a spacer..

Exactly..........so they fit

So they don't fit.would 300mm discs be better,

Why is that disc drilled on one half and grooved on the other?

Of course they fit, you just need to add a wheel spacer, also an adaptor bracket is required too.

Your gearbox doesn't fit without some additional linkage, the engine doesn't fit without a spacer bracket on one side.........

Dave couldn't make his mind up when he ordered them?

I asked for drilled and grooved so they gave me 50% grooved and 50% drilled

Good shout on the brakes, I have a slightly smaller (295mm) Alcon 4pot kit which fit under my 15" front wheels. Originally purchased for track use to cure the my issues with overheating brakes but I know find myself driving a bit faster on road now as well. The original brakes are fit for purpose IMO but they never inspired confidence. I now have a nice solid feeling progressive brakes with a good bite.

If you want to hear more of my thoughts on the subject then have a read through this:

Great looking set up Dave , pm also sent

A fantastic upgrade, possibly the best single thing I did on my Griff. The spacer required to fit 16 in Estorils is no bigger than the spacer require to reduce the ET by switch 16 rears to the front. They are a perfect fit.

Thanks Richard/all.

And to everyone's favourite voice of doom Daz, the reason I know they fit under my 16" Imolas is because David Ancill (Andav469) kindly confirmed he's tried these callipers under a 16" Imola (even though he has Estorils) and there were no clearance issues as long 12mm hub centric spacers are used.

My Brembos came from an EBay seller so were a punt, apparently the seller reconditioned them which it looks like he did indeed do, or at least he's tried to recondition them.

Sadly it looks like he's damaged the dust seal lips on two of the four pistons

It seems he's used the two screwdrivers bodge rather than the correct (but expensive) Brembo piston removing tool.



If the seller tried and failed to blow the pistons out with compressed air I can see how he moved onto a pair of screwdrivers to butcher the pistons out, which leads me to suspect they were seized in at some point and that could easily mean more horrors will be revealed when they're stripped and inspected fully.

To be honest where brakes are concerned I wouldn't ever risk just fitting a set of callipers of unknown origins, no matter how pretty they look. They will get a full strip and inspection, and as I also don't have the Brembo piston tool I think I'll leave that to the experts.

A full strip and internal inspection is essential to my mind, and from my own external visual inspection I already know as an absolute minimum these callipers will need two new pistons and if you're doing all that a full seal kit is a no-brainer.

So, yes chaps they look pretty, but the truth is they've been tarted up for sale and I'll need to sink a chunk more money in the things to get them to where they need to be.

Caveat Emptor and all that
