hey folks

 

im looking at buying new disks and pads for my car

 

only had it a week but i think it needs it

 

its a NA, Jap import

 

am i right in thinking that the front disks are 296 and the rear disks are 307?

 

does my car have drums or disks on the back? i assume its disks

 

also, which pads should i be looking at?

 

and last of all, any reccomended places to buy from? im not looking for a big brake upgrade at the moment so just standards please

 

thanks for the help

Disc brakes front and rear. The Supra was fitted with 2 brake options. If you're not sure which you have post up some pics of your calipers.

 

Smaller Brakes

Front - Calipers 2pot/Discs 296mm x 32mm

Rear - Calipers 1pot/Discs 307mm x 16mm

 

Larger Brakes

Front - Calipers 4pot/Discs 323mm x 30mm

Rear - Calipers 2pot/Discs 324 x 16mm

 

Fit new Toyota discs, you can get these from your local Toyota dealer.

Email Chris Wilson he does his own performance pads for both brake sizes.

Just be carefull your local Toyota dealer doesn't rip you off, there seems to be a big differance in price between all the dealerships.

 

Also stock pads and discs are more than up to the job of stopping a mkiv

I would highly recommend Steve Manley of Inchcape Toyota Oxford. He offers great discount for club members, did me a really good deal on a oil cooler. Should have been 333 quid and I got it for 278, which is basically without VAT.

also, seen some jobbys on ebay advertising grooved disks for £60ish a pair, should i stay away from these?

 

also seen on ebay a set of brembo disks and ebc pads for about £250 all round the car

 

im not sure what to go for to be honest

is it alot of work and money to upgrade to the bigger UK spec brakes?

 

or is it just as good to replace them identical disks and pads?

 

im not going to be doing any performance modding to the engine other than an exhaust so i may just keep them the same size

 

although for asthetics, bigger brakes to appeal

As said they are the smaller brakes.

 

It's straight forward swapping to the larger brakes, just a case of removing discs and calipers and replacing with the larger ones. All parts can be bought brand new, price would be £1K+ front and rear for everything.

 

The larger brakes are very good and are well worth fitting. If you don't want to spend that kind of money though, then a good set of pads, decent brake fluid, braided brake lines and a stopper for the brake master cylinder will make a big difference to the pedal feel, bite and fade.

 

Chris Wilson does some good fast road pads.

 

Use genuine OEM Toyota Discs.

DOT 5.1 Motul RBF600 or Castrol SRF brake fluid.

maybe a silly question, but what does a stopper do?

 

With the engine ticking over get someone to press the brake pedal and you'll see the brake master cylinder flex. The stopper braces the BMC to minimise any flex, this helps firm up the pedal feel and transfer more of the braking power to the calipers.
