Gen7 Front Brake Discs

[nkundalia]

Hi All,

I've recently had my 50k service done and was told i needed new front discs and pads, but they quoted my £320 for the standard replacements, I wanted to know if I should go for something a bit better, but would not know where to start or what to look for!

Any guidance will be greatly appreciated

Thanks

Neil

If thats the price MrT quoted you i`d be inclined to get down to your local friendly independent garage and get a quote. You should be able to get it done a lot cheaper. I`ll give you an example. I just replaced my front discs and pads on my BMW 5 series. Original equipment ATE Discs were £30 each and the ATE pads were £28 Thats less than a ton including the dreaded VAT. Took an hour to fit them. So a reasonably priced garage would probably charge £40-50ish.

A well known garage chain (whos name I forget at the minute - along the quickfit lines) did my front disks and pads at about £100 a little while back. They're not up to much, but they do stop me and they'll do for the time being...

If you're upgrading, take a peek at Mintex products - I hear nothing but good stuff about them!

Buy the pads from toyota, get the disks from wherever is cheapest (try some places on the Internet). Either fit them yourself (it's an easy diy job), or get your local garage to fit them. Should be less than an hours work.

Cool, I've trying to do some research, and there different types of disc, ie: Grooved, Driled and Grooved and drilled, is this a good thing, what's the difference? What effect will have on normal road driving?

Is there anything in particular that anyone has tried this good for a gen 7 140?

Thanks All

Don't worry about all that malarky, it's just gimmicks. ;) You just need standard pattern part disks (ventilated, but no grooves or swiss cheese holes).

[DefiantFrog]

Worth noting, the Pre-facelift front discs are smaller than the post-facelift ones... 255mm pre, and 275mm post, I think, but don't take my word for it.

I've been wondering about drilled / slotted discs against the standard vented ones, and logic says the standard vented ones should be better - more undisrupted surface area for the pads to grip, and cooled from the vents running between each surface. I'll wait to be corrected by someone who actually knows what they are talking about though!

Cross drilled discs are so called because of the holes drilled into them (!). These holes help disperse heat, reducing brake fade.

Grooved discs help to de-glaze the pads. This ensures greater friction between the pad and the disc. They will wear them out faster though.

Drilled and grooved discs combine both technologies. These discs are therefore more expensive than x-drilled or grooved.

Here it is

You talking about gen 7 or gen 5 with the different size brakes? (The sizes you quote match gen 5 sizes).

Drilled discs a a marketing gimmick, nothing more. Thermal stresses make them prone to cracking. Not really convinced about slotted/grooved discs either. For road use they definitely won't be any advantage.

Neah, Gen7... Mine's a pre-face lift, and it definately has smaller disks than the post face lift. Like I say, don't take my word on the exact sizes, but thats what I remember...

Whats the difference between old and the face lifted model. Styling wise

Very little, it's hard to tell them apart. I think the rear lights are slightly different, and the front bumper looks different somehow, but I can't quite put my finger on it.

[Asterix187]

The front bumper is different because of the shape of the recess around the fog lights. On the older version is curvy roundish shaped, on the newer version its more defined with a sort of |> <| shape

[DefiantFrog]

The Facelift G7 has different rear light clusters, bigger front disks, different bumper (long slot along the front instead of a triangular hole with toyota Badge in, and the 'prongs' from bottom to top are at more of an angle), Toyota Badge is on the bonnet, and the interior plastic is a lot darker.

Thats all I am aware of, but there may be more...

I think, I've decided, based on what everyone say, that I think I'll probably go for the standard vented disc's, but i will go for the 275 discs, as they, according to the sites i've looked at and a few pounds more the the 255.

I was wondering why they were available in 2 sizes, at least that's cleared up.

Thanks for everyones help, I'm sure i will be back for more at some point.

I think you'll find that you can only fit the same size discs as you currently have. Otherwise, you will need different calipers, or at the very least different mounting brackets for the calipers.

I was told exactly the same thing a few minutes after I poseted that last message, thanks, I will be checking with EuroCar Parts, as they are now doing parts for all cars, Whehey!

[DefiantFrog]

Ahh, glad someone told you about the calipur mountings! Its certainly possible to put bigger disks on with the same calipurs, but like has been pointed out, you'll need to mess about some more with the mountings to get them to fit properly. And I think it is more look than function as well if you go that way. Where as I can believe that you will slow down a little better, it wouldn't be noticable, and I think you'll wear your pads down quicker...

[Asterix187]

If possible could you let me know what parts you used/are going to use and how they perform as i need my front discs and pads changing now as well on my 1999 Celica Gen7

Cheers

[Spuffington]

Asterix & DefiantFrog have pre-facelift.....check out the pic in my Avtar which is post-facelift to see the difference in front styling.

Also, there's a difference between the size of front brake discs on the T-Sport and 140 on the post-facelift. Not sure if this is the case between the 140 and 190 on the pre-facelift too?

Will let you know when i do it, but the useless bunch at the DVLA have just revoked my driving licence for some useless muckup at their end and I can't do anything until i get my licence back

gen 6 st205 gt4 , vented discs , no holes , no slots , stopping a 250 bhp motor with ease - why bother with anything other than stock ?

try www.brakesinternational.co.uk very good service and products

It`s a little known fact that Toyota engineers spent a lot of time studying the braking systems of a well known American manufacturer for the design of the ST205`s brakes. Visit their site HERE ;)
