Well its taken waaaaaaay to long just to get these sorted but its been worth it.

And this means something apparently...lol :-

and yes...I know i need to clean my wheels:-

I wasnt sure if theyd be done in time for Da Pod but me and my mate worked till gone midnight the last couple of days and have got it sorted.

Had lots of problems such as:-

Bolts required were different to that fitted to fit the Brembo calipers...The original bolts were a smaller metric thread size and the bolts required to fit the Brembos were a larger metric thread size.

The Brake hose connections for the Goodridge braided hoses were the wrong ones..females instead of males so new connections had to be flanged and sorted.

The original front brake disk didnt wanna shift so we got a "Fook off" great puller and it just popped off..lol

Guards got in the way so we just cut them off (could of bent them out of the way but I need them off for fitting these:-

Brake disc duct

there not fitted yet as i need to figure a route out for the ducting from the front fog inlet.

 

Performance in figures :-

Standard TT setup 100mph > 0mph = 7-8 secs

Brembo GTR setup 100mph > 0mph = 4 secs

 

To be honest the pads I tested the standard setup on were very low but still had full coverage.

But to counter that...

I think I may be able to get below 4 seconds braking on the new ones but the ABS started kicking in so I now need to get a switch fitted to eliminate the ABS for trackdays :tongue:

 

The conditions for both tests were:-

tested after 20 mins of normal driving

Flat dry road (private)

Left in third gear and no changing down of gears

Exactly half a tank of fuel (set of brake discs in footwell and spare set of calipers...lol)

 

standard TT setup:-

280mm discs

4 pot calipers and std pads

Dot 4 Fluid

 

Brembo GTR setup:-

324mm discs (DBA grooved)

oversized modified 4 pot Brembo calipers

Porterfield pads

Goodridge braided hoses

Dot 5.1 fluid

Custom alloy brake brace (Clicky )

 

BIG thanks to Smithy/AndyP/MJP/JMB services and all who supplied help on my threads for these.

Major recomendation for the DBA discs and Porterfield pads.

(I was impressed with a little touch on the DBA discs of a heat monitoring facility on them...)

 

The pistons are modified....

They are made out of Stainless steel instead of alloy..This is to stop the heat transferal from the piston to the fluid....

Also...

They have a "Castelated" head on them which allows air to circulate from inside the actual piston to stop the heat build up..These little race tricks will eliminate brake fade on trackdays.

 

Now I have these I wonder how i ever managed before....they just seem right for the car now and no longer do you have to worry about thinking "Fook...ive left the braking too late.

Its now more a case of "Why did you brake so early"

 

I have covered about 200 miles on them and have not had any signs of the dreded "squeeling" from them so looks like Porterfields are the nuts of a pad :duffer: Dont care how long they last...They work like a dream.

 

So im all set for the Pod tommorow but I know its only gonna want to make me get a move on with the supercharger conversion but thats another day...lol

you gunna try and modify those TT calipers then gaz?

yes mate. like the idea of the castlated tops. just wondered how the bottoms of the brembo pistons were finished. the stock ones have 3 pips on the bottom which i assume are to allow the fluid to flow underneath. i was wondering if there was a better more efficient design. tried looking at wilwood calipers but they are flat bottomed :shock:

 

pics below show a stock caliper piston bottom.

 

good pics eigh that my new phone LOL

Quick one matey, im helping a mate refurb his calipers on his lecagy turbo. His pistons are really rusty, whats the best way to clean them up while keeping the surface smooth?

use a pad called scotchbrite its like an engineering scouring pad will remove the grime but will not harm the surface like emery cloth. if they are too pitted they should be replaced as they will leak

Oh and whats the best way to take pistons out that are already pushed in all the way in. The calipers are off the car so i cant push them out using the brake pedal.

got an air compressor if so put a piece of wood or simular soft piece in the gap between the pistons. use an air compressor blow gun in the brake line input and keep fingers and anything you dont want to loose out of the way.

 

 

i used 2 screwdrivers VERY carefully in the groove of the piston and prised it upwards till i could remove by hand. be very careful not to score surface of the piston or bore of the caliper

blackmagic come back!!!!!!!!!!!!!1

 

i need to now if you just copied the original pistons on the calipers in stainless or did you modify it other then the castillations on the top.

what did the bottom of the piston look like etc.. i want to make these for a set i have but not sure on some of the details :bow:

 

!!!PING!!!

 

As if by BlackMagic.... He appears :D

 

lol... How u keeping bud?

 

As for the pistons...

Yes, we did just copy the original piston specifications but to within nearly zero tolerance :eek:

The originals were just coated alloy... we used non coated Stainless Steel.

The castelations were the only other modification other than the material.

(see here for more variations on the castelations tried n tested)

The original/standard pistons in my Brembo calipers were ones with a FLAT base... totally flat unlike your ones shown.

 

And TurboZ has indeed got the best set of anchors around :hyper:
