After replacing my front shocks i noticed that sometimes when driving my 1994 80 my brake pedel gets hard and engine stumbles when i try to brake. It is really hard to stop the truck but then goes back to normal braking after about a minute. It happens at random then goea back to normal. I checked:
Brake fluid
Power steering fluid
No vacuum leaks
Any ideas? Thanks
