Is this wheel cylinder leaking?
Posted by: NebraskaDave ()

My car has been pulling slightly to the left upon braking, so I am operating under the assumption that the right front brake isn’t fully engaging. I understand it could be any number of things, but I figured I’d start here. This weekend I installed a new Clark’s dual master cylinder, and everything feels good, but it stills pulls left. The rubber brake lines are dated 2008, so my assumption is that they’re not the problem. All of the fluid I bled out looked good, except the right front. It appeared to be streaked with red/rusty fluid. It looks like the brake components were replaced, I’d guess in 2008 as well. My concern is the wheel cylinder, does it appear to any of you to be leaking from the bottom right side? The fluid that is on the rubber boot was tacky, like grease. I found no evidence of dripping. I’ve posted links to pictures, thanks for your input.

I would clean everything off with brake cleaner, reassemble, test drive, and recheck for new fluid / grease. I agree is looks more like grease but it is really hard to diagnois a problem when it is dirty. It is most likely pulling one way because there is less friction on this side

Yes it looks like it may be leaking. How does it look under the boot should not be really wet in there and certainly not rusty. I do not think I would necessarily put a lot of trust in 10 year old brake hoses either. Tires also made of rubber are suspect if they are more than 8 or so years old is the current theory so....

Good pics, I'm looking at the surface the grease seal rides on, something looks wrong. Also, it looks like the inner bearing may have cut into the spindle. Maybe its throwing some WB grease.

Without removing springs or shoes, pull the boot back from the end of the wheel cyl. If there's moisture on the back side of the boot, the cylinder is leaking. If it's dry, it's a failed grease seal from that rough seal surface.

I wouldn't take any chances with brakes. 10 years can be OK for a hose but of course it depends on the life it has led. How often fluid has been changed, exposure to ozone, cold, wet, salt etc. I'd certainly be tempted to swap them out for what it's worth.

Cylinders are pretty cheap too. Are they the same for a dual setup?

Must admit I replaced the fluid in mine and it made the world of difference. What came out looked like gravy (British gravy, not your weird American gravy). Two hoses were replaced when it came into the UK but a full fluid replacement had not been done. I also had to replace the master cylinder as it was also leaking. I expect the cylinders to give up so when I visited the US last month I did pick up some new cylinders.

I see its a 63 and my experience with this is an LM. The rear brake is Vairy strong compared to front engine rear drive cars. I was trouble shooting what I certain was a front brake issue for weeks. Then I took it out to gravel road running between 5/10 MPH and hit the brakes hard enough to make it skid. The rear wheel skid, not the front.
