Had the brakes serviced (fluid changed, bled, pads checked) recently but brake problem getting worse. When the car is cold, I have to exert a lot of force for very little braking power. The problem seems to go away after the car is warm/been in operation for a while.

 

I'm thinking brake booster or master cylinder... any thoughts on which one, or how to check?

 

Can I replace these with parts from a different year Loyale? I'm in Mexico and can't find any parts so I'm gonna have to have them sent, but not sure if the booster or master cylinder from a 90 or 91 would work.

 

Thanks!

Parts for 1990 /91/92 booster and master cylinder the parts number are the same. I recone you have a seal problem due to age .
