603 Brakes

Can anyone tell me where brakes come from? Are they a Jaguar fitting and if so of what model?

Brake Discs are strictly a Bristol Cars item.
I spent some time researching and eventually bought from them.

ACCS also sell the Girling discs and callipers and they are the same as the 411 / 412.

All the parts are available for rebuilds from Contacting PowerTrack Ltd for your classic car brake parts

Thanks everone for the feedback and look forward to the Girling list.
I just thought that if the calipers were from a Jaguar then there was a greater opportunity of getting an aftermarket upgraded caliper if i need to rebuild or replace mine.

They are Jag front and Aston rear - I think

Sorry, haven't had time to scan the Girling parts lists. Will get to it asap.

In the mean time, from the list I can tell you this;

The rear caliper and handbrake assembly listed as used by Bristol are common with AC Cars, Aston Martin (that will be DB5 & DB6), Iso, Jensen & TVR.

Some of the front calipers listed as used by Bristol are common with Jensen only - LH Caliper 64032280, RH 64032281.

However, there is another front caliper used only by Bristol;
LH 64032175, RH 64032176

The parts list includes 9 different pairs of front caliper part numbers, used by a variety of car manufacturers. The internals of all the calipers are mostly the same, apart from some differences in brake pads, so I assume the main differences lie in the caliper bodies, which probably means the mounting points (bolt holes) will be different.

Finally got around to scanning and uploading it. It's in the 411 resources section here (you need to be logged in to view/download the file).

NB: I don't know for sure these are what's on the 603 (see my previous comments re most likely caliper part numbers).

Many thanks for the link.

It's a real pain that there are no parts lists available for these later cars. We can thank TADC for that!

Hopefully a 603 owner can contribute some information. However, if the brakes are the same as the 411 and 412, which is quite likely, then they are Girling brake calipers.

Some components are common to all Girling calipers at that time, such as pistons, but other parts are specific to certain cars. I will scan and post a Girling parts list later on, which lists the variations of the design and which other cars used them.

If the car has been standing around unused for a long time it is likely the skirts of the pistons have rusted. If you rebuild the calipers I suggest you use stainless steel pistons. I have previously bought them from a guy in the UK who advertised them to the AMOC (Aston used the same caliper pistons from DB5 onwards).
