Title: Brake Bleeding
Post by: lanciamad on March 17, 2009, 02:41:33 PM
I'll be fitting my Goodridge braided brake lines soon, is there a right and wrong way of bleeding the system ???
With regard to the front calipers, bleed rear hose first then front ???
Does the rear need to be loaded, due to the rear brake proportioning valve ???
For brake fluid, i will be using a high boiling DOT 4 racing fluid, recommended by alot of the saloon drivers in the Castle Combe championship, which apparently is also compatible with DOT 5.1, and £13.50 for a litre aint bad as well ;D

Yes most definitely.

Do the front brakes first - with the front jacked up, bleed the front circuit (nipple closest too you) on both sides first and then do the mixed circuit (nipples furthest away) again on both sides.

With the car then on the ground do the rears - as a note to anyone replacing the rear pads - when the pistons are screwed back, the lines on the brake pad face of the piston should be facing upward, so that all the air can be bled out.
I would also advise brakes to be bled every time pads are changed - air tends to get in, not always but some times.

No real need to load the rear, just bleed them and you will be alright.

Oh .... and be careful you don't shear the bleed screws, use heat if necessary and clean the threads thoroughly. 

Hope this helps.

I'm reding this.

Ok for the front first,

but for the mixed circuit , I think we have to bleed the farest caliper first... the back right, anthen the left en the front right to end with the front left ...???

This procedure is wrong???

If you have access to a compressor the compressor driven vacuum bleeder is my favourite. I have used mine with success on all cars I have tried it on including some nototiously difficult ones. Start with the caliper furthest away in the mixed circuit.
