bedding them in at the mo, so just light braking.
but i expected to have that enormous stopping power
feeling with even the lightest of pedal push?
or will they just come good when bed in?

 

You say AP but your pict says Brembo .

pmsl

 

ok the disc's

 

Are you sure as the grooves on the discs arent from any AP I have seen,
Normaly I recommend 200miles carefull driving before testing them but this also depends on the pads on how they are meant to be beaded in.

Mark

 

I would of thought the pads were the main thing causing a crap feel on the pedal.

Aren't they a bit of a overkill on a 300hp chavalier

 

300! i'm surprised you can see what your typing
with your head in a bucket of sand

 

there 110% AP

 

Ap dont make discs

 

well gen me up then? cus these came in ap boxes sealed and have ap part no@s on?

 

well this is gonna be an interesting thread

what are the calipers off?

 

I see you just changed your siggy

 

If AP dont make discs then why is it that they are the only people to supply them for the Lotus Carlton

 

gen ?

.

 

I have a dozen of those boxes mate so I am quite sure AP DO make discs.

As AP do brake kits I'd be suprised if they use someone elses discs in their package

 

i thought AP only had about 8 grooves on them.

why have they changed them,or made different types.

 

@ your sig

There is no H in Jonny either

 

I spoke to AP about getting discs for mine and they said they only make the calipers and then put me in touch with a company called BG developments who make the kits up for each car.

 

Mike Rainbird has supplied my mate with AP discs for his 3 door several times.

 

thats for brackets etc i would imagine. but AP manufacture discs and calipers ????

I could be wrong

 

you forgot the 's for euan

 

Ill take them on the chin chop

 

 

They are ap disks but the calipers are Brembos ment for a Jaguar as it the same kit as ive just got from Reyland.

 

I found that when i went from 4pot 330mm APs
to 6 pot 355mm APs they did have less bite and feel softer in use
but they worked well when hit hard

 

what pads are you running? also is the master cylinder man enough only ask because i know little about vauxhalls!

 

ds2500 iirc the number!
master cylinder i have no idea! maybe marco could gen us up?

 

I had no problem with my Ferodo 2500's

Are you using the OE Master Cylinder ?

 

yeah y, summat i need to know?

If you want to get ultra sharp braking just touching the pedal then you need to fit a bigger master cylinder. This will push more fluid pressure down the brake lines for a smaller movement of the pedal.

Fitting bigger brake calipers often reduces the sharpness of the pedal as they have a bigger piston area and therefore takes more fluid pressure to push the pistons into the pads etc. Therefore fitting a bigger master cylinder will compensate for this.

But for a track car it is good to have a weaker setup to allow for more modulation on the brake pedal (depending on driver preference)

Also pads can affect it of course, but you have DS2500's and they are good!

 

As above mate, its important to get the right MC if possible.

I left mine alone on the nova but have have recently tried a astra 16v cylinder to improve the feel of the pedal.

Not sure how well its worked yet as the car hasn't been used

 

my ap 6 pot 330's on ferrodo 3000 pads made the back end all floaty on serious stopping time to wind up the front suspension after that

 

well i thought then kind of discs have to be hot to really work good?
