Thread: Can't Stop Me Now !!

    Default Can't Stop Me Now !!

    A friend of mine drives a car of 'roughly' equal weight to my Vectra VXRD and is having trouble with his brakes.

    Its not that the brakes aren't good, but they are not brilliant and he wants more stopping power. But the catch is... without spending tons of cash.

    The standard size disks are 300mm and he recently upgraded to grooved CRN Product Disks and Mintex brake pads. But he still isnt happy with the stopping power.

    He has looked at 4 Pot brakes but gets the impression that they will not be suitable as his car weighs around 1500Kg and we have seen articles suggesting that 4 Pots are only suitable for cars less than 1000Kg.

    We have looked at Alcon, AP Racing, Brembo, Tarox but they are all around £1650-£2000 including fitting etc for 6 Pots....

    Are there any quality alternatives !!

    Oh, it was suggested that he looks at the Seat Leon Cupra R Brembo set up as they offer 4 pot kit 330mm disks for around £800 + fitting. But they are 4 Pots....

    Cheers

    I wonder if there is something wrong with his brakes! All Vec C's / Signums have 285mm fronts, except the 2.0T - 302mm and the 3.0V6/2.8T/3.2V6 - 314mm - so if he has 300mm on a car of similar weight it should be stopping him just fine.

    Why do you think that? The Vec C / Signum weighs, on average, around 1500kg and isn't even running four pots - I think it's actually only one pot that distributes the braking force. He sticks on four pots and he should notice a marked difference.

    Afraid I can't help with suggestions of products - apart from the usual (expensive) suspects.

    It would help to know what the car is first... if it's a Bora or similar, robbing the brakes off a Cupra - or even a TT - would be a very good start.

    However, as I'm sure you're aware, the best first step is to get some braided lines, some fast road pads & maybe some drilled & grooved discs from a reputable manufacturer

    Agree with what the other lads have said and would probably be looking into the possibility of a fault with his standard brakes rather that spending X No. hunderds of £'s for an upgrade,

    Yes the LCR has 4 pot brembo's but LCR is no where near 1000kg never mind less than! they weigh in at 1376KG IIRC

    IMHO 4 pots will be more that adequate for what your friend wants and will definately be a suitable upgrade over standard

    im looking at 4 pot brake upgrade for my GSi (not a light car) mainly because i cant justify the price for the 6pot.

    i think your friend may have faulty brakes (small leak or a cracked disc/pad).

    4 Pot Brakes are better than the single pot he has now.

    Pushes from both sides 2 pots in the caliper.

    Very good.

    OK.. I will suggest he checks out the possibility of faulty brakes...

    But, when I spoke with 888 about my AP Racing brakes, AP Racing said that they would NOT suggest I take the 4 Pot brakes due to the weight of my car, and they would not authorise or suggest a 4 pot system. ??? - Which is why I am getting the 6 Pot ones.

    Logic tells me.... why cant I use 4 Pot brakes on my car when the VXR uses single pots ???? I just dont know the answer ???

    There are plenty of cars running around with far less brakes than 4 Pots, so why have AP Racing said 4 Pots are not a good choice for my car ??



    Oh, and the car in question is the Mk IV Mondeo 2.0 TDCI Zetec

    4 Pots might not dissipate the heat as well as the 6 pots...
