| the brake light switches should be the same. The warning light goes on if one switch trips quicker than the other, so if the the switches are different the warning light could be on even if your brakes work fine do to different pressure tolerances of the switches. I have reused the switches several times. |

Well I managed to get the master cylinder out last night. I had let the brake line connectors soak in WD-40 overnight and they came lose with no issues. The question I have now is about the brake switches. They both look identical. Are they? I don't see a separate listing in the parts catalog that says either one is different. So do I just buy two of the three prong brake switches?

I agree. I repaired some dash wiring today. I guess after some aging the terminals become brittle and crack so I had to replace a bunch of wire terminals. When I was done I did notice that the brake light is on constantly. I'm thinking that tomorrow I'll drain the gas tank and remove it since I need to check the sender in the tank and I need to check the fuel pump for the gas heater. I think it will make changing out the master cylinder a lot easier. Thanks for the help guys.

You may well have worn or hardened seals or you could have trash in one of the compensator ports (or whatever they are called). Either way a new master cylinder is probably the best way to go. |

The brake warning light is on my list of things to check while I have the dash apart this week. As far as I can tell it is not working at this point. I have the dash apart to repair the odometer and the fuel gauge (both of which I fixed last night). None of my dash lights (outside of the spedo now) work and I plan to go through them all. The wiring inside the dash has had some fingers in it in the past.

| if you are not loosing brake fluid, then id consider a bleed job or recheck adjustment. that the only thing it could be IMO |

| Other than OE German master cylinder units the other (country of origin) outlander units fail just some sooner than others. |

I'm draging this post up from the past. I'm having the same problem as the OP. The brake pedal is very random. The PO of my car had a shop rebuild the the brakes at each wheel and they did a great job. They replaced all of the cylinders, shoes and hardware at all wheels. I've adjusted the shoes and the pedal is nice and firm and the car stops straight and great. The problem is that the point that the brakes engage is random on the pedal. Sometimes they go straight to the floor but the next pump of the pedal they are up to the top. Sometimes they are half way down and at times they are at the top like they should be. It's very random. The master cylinder appears to be the original so I think my first step will be to replace it but I was curious as to what the OP of this thread did to correct the problem. I have no problem replacing the m/c but I don't want to do it if I don't have to. Any advice would be great. Thanks.

No beam adjustment. Only the brake components were removed for cleaning, replacement and painting. Suspension was blasted and painted in place.

Did you adjust the caster? It looks as if the beam is leaning back a bit.
Great looking job! I hope I can get mine looking as good. |

Brakes are everything. Here's a photo of my start on brake restoration. Only new parts in photo is the shoes and cylinder. Everything else was restored by sandblasting and polishing with a vibrating polisher. Hi temp engine paint used for painted parts including brake drum (not shown)
Check out the sandblasted shock with orange metal flake paint.

| Thanks for the help, I will hopefully be working on it soon, we'll see if I can afford to do the whole brake system or not. |
