Brake line copper washer size? 2018 Mazda CX-5

[Gold Star]

I replaced the calliper on my 2018 Mazda CX5 removed the brake line and reassembled it using the same copper washer now its not bleeding properly. What is the proper size crushed copper washer required.

What do you mean by not blending properly? Is it leaking?

Yes the brake line attached onto the calliper is leaking at the bolt connection I belive its the crushed washer thats not sitting tight enough. I just checked with the dealer and they have them in stock no idea of the size for $1.85 a piece it works for me.

Banjo bolt gets torqued at 21 ft lbs. Drawings show two gaskets get used, one on each side but mine only had one when I replaced the brake hose.

Thanks for letting me know I will get 2 washers and possibly I had one stuck onto the brake line bolt itself and thanks for clarifying the proper torque specs on the bolt.

Here is a TSB to replace the rear disc brake calipers for dragging issue:

TSB No. 04-001/18: Noise from Rear Brakes Due to Brake Dragging

These 2 copper “gaskets”, p/n: 9956-21-000, always need to be replaced when you replace the caliper. It does show 2 gaskets (D) for each caliper.

Torque values:

You could probably get those at Home Depot for half the price, all they are is copper washers, I think they're size M12 maybe smaller
