Bleedin Brakes :crap:

[Matt Cole]

Well all the gt's I've had over the years the brakes have been pony. Don't care what any one says the calipers are gash, tiny discs and a less than efficient bias set up. For 25 years ago maybe they were top stuff but compared to modern braking systems very poor. Replace I say with the best you can fit.

[Brigsy]

Most modern systems have abs and have loads of servo assistance though matt you cant really compare. I always notice on new cars that you only need to tap the pedal at lower speeds and you feel like your going through the windscreen, but not necessarily better from high speeds!

Good working standard setup with proper pads and decent fluid is easily good enough for 200hp, if you were going for more or a heavier engine i would upgrade though.

Just incase anyone is ever doing something similar in the future I have now spent a small fortune on Master Cylinders from Reno to save you the cost in the future....

So heres the info:

I bought a 197 Master Cyinder - Its actually 4 Ports, so would be a direct fit but the position of the ports are different to the R5 / 172 MS although they are all M10x1.0.

Part number 7701208880 - Lis Price £77.62

I also bought a 172 Cup Master Cyinder.

Part number 7701205739 - Lis Price £88.29

Now two of the ports are M10x1.0 the same as the R5 but two are M12x1.0. So Insead of changing the brake line fittings I made some brass adaptors to allow fitment of the standard brake pipes..



So I think I'll just go with the 172 cup MS and see how that performs!

How will other people get a thread adapter? Is that brass strong enough? Won't crack with the steel (or they also brass?) pipe bolt thingy tightened overly hard into it? It is the brakes after all. Can't take any risks.

You don't need one, just get new lines made up with M12x1.0 fittings on one end.

Plenty strong enough, you don't need to over tighten the fitting into it as it seals on the cone.

It is the brakes after all. Can't take any risks.

Very true, I wouldnt, thanks for your concern though

or just use the golf rallye one i've mentioned about 3 times now, and its direct fit, and works with 325mm hispecs so probably as big as you can go

GTT and golf master cyl comparison just incase no-one heard me mention it before... lol

i recon i must have same dissapearing posts as mart

I had a look for the Peugeot ones details in the articles, couldn't find. Then I realised it might have been in the 1 years data we lost.

But I think that was a direct swap as well.

gsf p/n = 652vg0250 = £34.40 + vat
or 652vg0251 = £42+vat (better make)
