Front rear disc brakes

Postby 7573 » Mon Jul 08, 2019 9:19 pm

I have install s10 disc in front of 75 vega, worked fine. I then installed disc beake
On the rear, i can get fluid out the back bleeders but no pressure.

Do i need to get a master cyl for four wheel disc brakes. I think what i have. Ow is front disc and rear drums.

Are the rear bleeders on the top of the calipers ?
you may need a new master cylinder with a larger bore.

Did the master cylinder go dry at any point during the conversion? If so, you'll need to remove the master and bench bleed it. There is probably air in the master still.

Hi chuck we thought that might be the problem
So we did bleed it and still no difference.
