So today I fixed my brake lines, and took my car for a drive for the first time. Every time I shift it into second, it grinded. 1st, 3rd,4th,5th were all smooth, it was only second gear. also sometimes the clutch pedal would get stuck down. So what do you guys think is up?

 

most likely, your clutch hydrolics are bad or need to be bleed, but in most cases youll wind up replacing both its a pretty simple task and doesnt cost too much, under 100$ if you know where to look. btw ive herd its a good idea to go ahead and change the flex hose to just in case.

 

I'm going to replace the slave cylinder, hopefully that fixes it.

 

It really is reccomended that you replace both cylinders at the same time.

 

What are both cylinders? Can I just replace the whole unit on my firewall?
