Look at the chart that Alex linked to, and do the calculations on the piston surface area for UK's and Brembo's and you will see people are not BSing you. Are you sure you have UK spec brakes ? If so maybe something is not quite right with them. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Personally we've found them great, but have heard of numerous people lately claiming that they warp under hard useage.....had ours a year.....with more than a fair share of hard usage. I refered to aps being not so good, as thats what the mpression I got lately on here from various tuners, thus thought thats what everyone thought, so reffered to them not being that good so that most could relate....if u know what I mean. Think the world of AP personally..... Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Hi Martin, ummm....you and Akex are right in theory, it just doesnt seem that way in practical terms, I dont know why?? I am pretty sure we have uk brakes, got them from toyota airdale, and they weigh a bomb too....... Quote Link to comment Share on other sites More sharing options...
Gordon F Posted June 11, 2003 Share Posted June 11, 2003 Ali I remember seeing your car at South Mimms before the Boxhill meet. It had J - spec brakes on then. Have you upgraded them since? Quote Link to comment Share on other sites More sharing options...

Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Oh and they has always been play in the pedal, since purchase...? Quote Link to comment Share on other sites More sharing options...
Terminator Posted June 11, 2003 Share Posted June 11, 2003 There should be no play. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 ummm....thats what we thought during purchase, but then heard that the brakes may need sorting or just fluid. Cheers Phil! Quote Link to comment Share on other sites More sharing options...
Terminator Posted June 11, 2003 Share Posted June 11, 2003 I recently bled just one calliper on Justin's Jap front brakes. I think he said they felt better than they had felt before. Just a small amount of air makes a huge difference. From what you describe, the brakes should be checked. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 11, 2003 Share Posted June 11, 2003 Will do that Termie, ASAP......oh what helpful lot u are on here! ........ ....... Quote Link to comment Share on other sites More sharing options...
Nick Posted June 12, 2003 Author Share Posted June 12, 2003 If I could be sure they´d fit I´d go for a set of AP´s, I have no doubt they´re a better kit. A mate of mine had a set on his Imprezza Terzo and they were absolutely awesome...Obviously a different car but the OE brakes weren´t too shabby to start with... It´s not just one off stopping power that I´m interested in but fade too. The Jap brakes are absolutely terrible for it and it seems to be the conclusion on the board that the UK´s are good, if not better for a one off stop, where as the Brembo´s will go the distance fade wise. Thanks for all the replies, not sure what to do just yet.... Quote Link to comment Share on other sites More sharing options...

Steve Cargill Posted June 12, 2003 Share Posted June 12, 2003 Originally posted by u_ali Yes Gordon, last week.....im 100% they are UK spec....if anyone would like to sit in it, with me dad so that we may have thier opinion is more than welcome at future meets. If you got them fitted last week did you do a complete fluid change at the same time? Did you put braided hoses on? What pads have you got and did you bed them in properly. Did you do front and rear? As Phil said, there should be NO play, they should give you a feeling of massive confidence in them, if not something is wrong. How do they compare to the J spec you took off? (I think we've moved from the AP discussion to "you may have a problem with your brakes and are trying to help") Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 12, 2003 Share Posted June 12, 2003 Hi Steve, The system was bled at Option, with new fluid aswell(dot 5.1 I think) The pads are OEM uk pads, no braided hoses, although upon leaving the mechanic did say there was play present and that Braided hoses should sort it. They are better than the J-specs, but then again our J's were seriously warped quite a while before fitment, me dad says they di give some confidence, but can no way supply the confidence of AP. The system is going to get flushed and re-bled as soon as I get the hoses, then will let you know if thiere is any difference! Cheers All.

That is bollox, does he think the stock system should have play in it until you replace with braided hoses normally ? Quote Link to comment Share on other sites More sharing options...
B3any Posted June 12, 2003 Share Posted June 12, 2003 With all this talk of brakes, i thought i'd throw my two pennies in. I've got J-spec Brakes, with standard pads, but i had a track day coming up.... Couldnt afford the upgrade so just uprated the pads to Porterfield Full Race pads, fitted them and noticed improvements, went on the track day must have done about 20-30 laps, no brake fade, and excellent stopping power, however i didnt realise how good they were until i took them out again and the standard pads were so shiteeee i almost ran in the back of people, so i dont think its so much the discs but the terrible pads that are put with them. Never been in a UK setup so cant compare, have been in a Kad setup with UK rears and they are very impressive...... But just wanted to say that i think the pads are the culprit more than the discs themselves when it comes to J-Spec. Quote Link to comment Share on other sites More sharing options...

Nick Posted June 12, 2003 Author Share Posted June 12, 2003 20-30 laps without any fade on J specs!?!?! I´ve got standard discs, uprated pads supplied by Chris Wilson (not the noisy race pads but the less effective road pads, still voted by people on the board as being very good) braided hoses and castrol SRF fluid. Assertive driving on the road leaves me without any stopping power, f%&k taking it on the track.... Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted June 12, 2003 Share Posted June 12, 2003 Originally posted by eyefi never had uk's fade, ever. I have, but I am also on my 3rd set of front disks & 2nd rears. Warped & cracked the others. I now have a full cooling duct set up so lets see if that helps significantly. Quote Link to comment Share on other sites More sharing options...
Guest Usmann A Posted June 12, 2003 Share Posted June 12, 2003 Interesting input, Martin, yes that thought did occur to me also, it seems that most tuners would rather mod it, to solve the problem rather than find the actual cause and rectify. Hi Terry, You are still running stock UK's on your single setup.......wow...... ..... What do guys reacon could be wrong, biggest thing would be brake servo, any ideas off the top your head??

Gordon F Posted June 12, 2003 Share Posted June 12, 2003 Originally posted by u_ali What do guys reacon could be wrong, biggest thing would be brake servo, any ideas off the top your head?? Being as you've just had the new brakes fitted, I would say that they haven't been bled properly, or maybe one of the unions is leaking Have a look at the inside of all the calipers to make sure there are no leaks. They should have used new copper washers on the brake hose / caliper union. Braided hoses will make a small difference, but it's not night and day......

Guest Usmann A Posted June 12, 2003 Share Posted June 12, 2003 I understand Gordon, if its one thing I've learnt is that dont expect too much from anything, especially when adding modfications, unless your going to do a TERRY S-spec... Will give it a good once over, and then get a local, to fit them hoses and bleed the system properly, and give it a through inspection aswell.
