Brake Upgrade Information

[Gerald-TVR]

Hi All
I have been thinking recently that it might be useful to collect in one place all the information gleaned over the years by people in the S Forum and add subject based information in the FAQ area.

As an example it might be useful if Mark Prince mep12345 produced a note regarding location of filler caps and explainded to us laymen pros and cons.

I have been vaguely thinking for some time about upgrading my brakes and I know many people have done that very thing but I cant get after the information as the search engine is down, again, so I would be happy to collate information from all who have upgraded into a single thread.

If you could send me information under the following headings for:

Front brakes
1 New disk diameter
2 Donor of new disk
3 Donor of appropriate calliper
4 Addition calliper information eg 4 pot etc
5 Spacers (if any) required
6 Minimum inside diameter of wheel to accommodate
7 Source of parts
8 Photographs if available

Rear Brakes
1 New disk diameter
2 Donor of new disk
3 Donor of appropriate calliper
4 Addition calliper information eg 4 pot etc
5 Spacers (if any) required
6 Calliper mounts – if converting from drum brakes
7 New drive shafts – if converting from drum brakes
8 Minimum inside diameter of wheel to accommodate
9 Source of parts
10 Photographs if available

Have I missed anything? Please add any other information you consider necessary

I have created a new email address to only receive this information [e-mail] (note underscore between Gerald and tvr)

Norm,

The filler caps one is already there on a thread called "stirring a hornets nest" but even when the search engine is working I find I can never find it. I think Barkychoc stared the thread.

BTW mine works both ways round so don't care anymore

Hi i put a HI SPEC brake kit on my s2 280mm discs 4 pot billet calipers Mintex pads all in £540.00 ive put 17" wheels on my car but 15" will fit as for upgrading the rear if you have this kind of upgrade up front you do not need to upgrade the rear you can stop on a postage stamp!!

[Gerald-TVR]

Hi Jason

Any idea of the donor car(s) for disks/callipers and did you source it as a complete kit?

Front brakes
1 New disk diameter = 260mm
2 Donor of new disk = Sierra Xr4i or Later model with ABS. DO NOT USE Xr4x4 disc offset is wrong for 2WD applications.
3 Donor of appropriate calliper = Sierra Xr4i, Xr4x4 or Later models with ABS. (Thats right Xr4x4 Caliper is OK but not disc).Make sure you also get the caliper mounting bracket the caliper is no good on its own.
4 Addition calliper information = Piston diameter in this caliper is 60mm over original 54mm.
5 Spacers (if any) required = None
6 Minimum inside diameter of wheel to accommodate = Any
7 Source of parts = Invariably bought secondhand then rebuilt.
8 Photographs if available. I'll see what I can find.

Notes: This is Griff / Chim 500 spec.
You will also need new brake pads.

Norman,

It may be interesting to add info on the dimensions of the flexible brake hoses to this thread (would make it easier for people replacing the hoses or upgrading to braided hoses). I say this because my cars hoses were quite unusual apparently...

To get things started I have a '87 S2 and the rear flexible hoses are: 200mm long (excluding threaded sections), 3/8 UNF thead at each end which is 0.88in (22.4mm) long.

Ralph.

Its a HI SPEC early chimaera kit it fits straight on, i made my own braided hoses just got the bits from local hose and hydraulic stockist. i got mintex pads with the kit £60 but cheaper ones are an option. they do cheaper kits with smaller discs they are listed on the web site as sierra brake kits

Hi,

These were on my S3C when I bought it.



Discs are approx. 280mm. Calipers are Brembos.

I presume the calipers at least are from a later TVR, can someone tell which?

Ta,
Gary
p.s. will try and provide rest of info for thread!

Hello Norman. Did you progress the idea of capturing all the brake up-grade options or did you decide life is too short?

[The Lukas]

Thanks Norman, this will help

Request was answered by roars of silence and I gave up

I remember someone posting a very helpful description of upgrading rear drums to disks using Sierra parts - have tried to find it, but with no luck - think it was back in 2006 or early 2007.....

[GreenV8S]

Lee Knierian did that conversion and I think was offering to sell kits for it at one point, but I haven't heard from him for years.
