Seat cupra 280 brake bleeding

[Leonmb]

Hi, I’m changing my discs, pads, braided hoses and doing a complete brake fluid change. Do you just bleed each caliper like normal or is there something you have to do with the ABS? TIA

General rule of thumb is start with furthest caliper from master cylinder if doing a complete fluid change

I'm sure I saw somewhere that it's best to use a pressure bleeding kit.

Thanks!!
Does anyone know how much brake fluid I will need for a complete change?

 

[Count Drunkula]

2L should be enough

 

[Leonmb]

Nice one! Do you know how much the system holds exactly? I know i will need some for bleeding through

When I did my mk6 Golf R I used 1.2L .

Can't see the cupra using much more than that

Got the fluid but it says this on the bottle:

It should not be used in vehicles fitted with magnesium alloy cylinders or reservoirs. Silicone type assembly compounds should not be used in conjunction with this product.

Does anyone know if the Cupra has magnesium alloy cylinders or reservoirs?

Thanks in advance!

What DOT rating is it?

 

[Leonmb]

Dot 4

I'd be very surprised if it has magnesium components, and you don't have to worry about silicon in the brake system.
DOT 4 is in widespread use, suits nearly everything but Harleys.

They must have some magnesium content? As I take it they are cast aluminium?

The OP refers to components of mainly magnesium construction, which are reasonably uncommon on everyday cars. I've used DOT 4 and 4.1 on all my bikes and cars with aluminium brake parts for many years without a problem. It has been the specified fluid for all of them.
A more important thing is to change the fluid regularly, every two years at least.
