'91 Mazda 626 2.2 not turbo.
On especially cold mornings, when I first start out, the brake pedal is hard as a brick and very high, like the vacuum assist isn't working. It stays that way for 100 - 200 yards and two or three uses of the brake, then it goes to normal. Vacuum connection from the manifold seems secure. Am I gonna have to replace that whole stinking vacuum assist unit? I hope this is not a dealer item. They will bend me over the sink while some kid plays dueling banjoes.
Thanks for any help,
Hamish
