This is about the fourth braking thread on here that I have put my twopenn'orth into, and it has gone the same way as all the previous ones.
I do actually firmly believe that the 156 JTD 1.9 16v
from around 2005 for some reason
was fitted with inferior braking components. I believe this because several owners of that specific model, including myself have spoken about it at length. My daughter has a 156 with excellent brakes. But it is a petrol model from 1998 with a 1.6 engine. Don't think that tells me anything, does it?
To clarify - my car had this problem from new, it deteriorated slowly over about 18months to a point where, frankly, I might as well not have had any brakes.
Fact is, having considered many theories concerning fluid, pads, hoses, and god knows what else suggested by very knowledgeable people on this excellent forum, I opted for upgraded discs and pads on the front only and guess what? Problem solved.
That may not mean the whole problem is solved - maybe the servo is a bit on the pathetic side, maybe better quality fluid would improve the situation further, possibly superior hoses also, but hey, my car stops now. It didn't before (and I really mean that - it was potentially very dangerous). I am now very happy with what I have.
my 2pence worth:
I drive a 2000 reg'd 2L TS engined 156. From day 1 i felt the brakes were grand around town but when driving 'spirited' then faded very easily.
So i got 'red-dot' 20 grooved discs & XE14 'fast-road' pads & changed the brake fluid to Castrol Response Super DOT 4 .... as per David C recommendation.
Still I got brake fade, so much that i removed & binned the red-dot pads & fitted standard spec'd Delphi pads..... much better, but i could still make them fade.
So i went down the '4-pot' route.
1st attempt was fitting front Porsche Boxster 4-pot caliper with the 285 x 22mm discs ...... i was able to make the discs turn a dark colour blue before the brakes faded due to excessive heat in the discs/pads
i'll skip attempt 2, 3 & 4, etc.....
Currently I have fitted to my car the following:
* Cross drilled & grooved solid discs from red-dot racing with standard pads
* Goodrich Hosing
* 305mm GTA discs which have 5 grooves either side
* Radial mounted Ferrari 360 4-pot claipers with Brembo pads [ standard compound ]
* Goodrich Hosing
Brakes are BRILLANT, never been able to make them fade
This is using the standard, for that year, 2.0L servo & abs system.
NOW for the real confusing bit......
I fitted the vented calipers & mounting brakets, Delphi pads & the 20 grooved discs to my mates '98 1.8 TS engined car & they are working VERY well on his car.
I've spend alot of time & quite a bit of money to get very good brakes, he inherits my 'cast offs' & have almost as good of braking ...Go figure
