Im using dual master set up with a bias bar. Now the SVA say that i have to have some form of showing whether the brake fluid level is low. The choices are see through reservoir with a line showing the minimum level or a low level light switched by a switch in the reservoir. Now i know you can by seperate reservoirs that are SVA compiant but they are pretty expencive.

What i was wondering was if anyone has got through the test with dual master cyls with integral reservoirs and how did they do it.

The low level indicator has to be visible from the drivers seat with a test facility operated from the same position, usually via the handbrake mechanism, to show the bulb hasn't blown. If you have dual cylinders do you have to have them on both reservoirs?.

yours, Pete.

i fell into this trap with the 1st locost i built basically both brake cylinders require the low level warning but can be on the same indicator the only way to do this is to buy 2 level caps from the likes of merlin motorsport be warned they are expensive £40 each . That why i'm going twin outlet remote this time round .

Yeah it looks like its gonna have to be two master cyls and then a seperate reservoir with a switch but at £40 its not what i need right now......

I have twin wilwood master cylinders with integral reservoirs and Ian Grey at ST said to use Mk 4 Escort caps. Should be a few quid from a breakers.

Ive heard that some BMWs have a seperate reevoir with dual outlets and low level warning , it might be worth a look in a breakers.

The early 80's BMW 7 series has a twin outlet seperate reservoir with a test button.

Slight diversion, but can any of you dual cylinder users enlighten me as to how to decide which bore sizes to use? For info I'm using cortina front and sierra XR4x4 rear callipers, I assume that there is a calculation based on piston areas (calliper and master cylinder), pedal ratio and vehicle weight

Cheers Mick

Have a look at Lada's (yes really), they have a reservoir with twin ports too....

Mix, I have used 0.625 cylinders with the same brake calipers as yourself.

Why can't you use the reservoir from the dual servo master cylinder in the ford?

S'OK guys just bought some master Cyls and a resevoir from luego £33 each.
