1989 Chevy P30 Brake Hose

[cdawley4]

Hello,

I have a 1989 Holiday Rambler built on a 1989 Chevy P30 Chassis. I am currently working on gathering a parts list for replacing the braking system, from the master cylinder to brake hoses to calipers. I keep reading posts about using braided brake hoses, but can’t find anything at any of the parts stores.

Does anyone know where I can buy braided brake lines for replacing the rubber hoses?

I figured since the rv is 35 years old and I don’t know the maintenance history, best to start by replacing everything with new parts.

I live in the Griffin, GA area and have seen posts regarding brakes from a member in McDonough, GA.

Any information will be greatly appreciated.


Thanks,

Summit racing is a great site with a great search feature for stuff like brake hoses. That's where I'd look for braided brake hoses. But brake hose failure is a pretty rare failure, though I had a 90 honda pop both front brake hoses, a few months apart, it wasn't in the 90's though and I don't know the whole history. Rock auto is another site to find hoses based on the vehicle, and the pictures in the search results. If that fails, go to summit and search based on length and hose thread on each end. Replace any rusted steel lines with cupronickle and get the tool to do double flares, it's easy with cupronickle and it will never rust. NOT copper PLATED steel, cupronickle or copper nickle alloy.

Call some hydraulic hose shops in your area. Most make custom hydraulic and brake hoses as well. You will possibly need to remove the hoses for them to copy. They may be able to do it if you have the dimensions and fitting sizes with pictures. Usually they make oem rubber and steel

I use Rock Auto all the time. That’s where I am planning on getting the calipers, master cylinder, and brake pads. I looked at Rock Auto and Summit for braided or stainless steel brake hoses, but all I saw was the rubber ones. Even looked on Napa and Amazon.

Trust me, rubber flex lines will work for many years. There's not many OEM brake systems that DO NOT use rubber ones. Unless you're going racing, stick with the factory style.

Yes, your almost 40 year old rubber lines can be replaced with new rubber lines, and do it again in another 30 years if you want. I've driven around 70 year old rubber brake lines, it's all relative, braided lines are still the same rubber inside, and are just as suceptible to failure from the inside, maybe a little more durable from external abrasion or impact damage.

Braided lines are mainly for looks. The wire does add a degree of protection if the line can rub on another part. But underneath it is just another rubber brake line.

Braided lines look cool. Unless you are racing there really is no advantage. I used to have a Winnebago Chiefton 22 on a P30 chassis. My son owns it now. Try going to NAPA. They should be able to get you replacement part numbers and from there you can cross to braided if you want. The P30 is a very common platform they used for years! I never had an issue getting parts. Unless It was driven in snow the metal lines should be fine. Crawl underneath and do a thorough inspection before you do all the work of replacing all those lines. The rubber hoses and flushing the brake system is a great idea though. Good luck!

Some sports car enthusiasts will use braided brake hoses, often with Teflon or other high end hose assemblies with the thought of longer life, and the reduced flexing of the hose under pressure giving faster brake response and better pedal feel. You're not driving a sports car here. I'm thinking this coach still has drum brakes in back and probably the hydraulic brake booster. Not performance braking here.

That said, brake hose replacement is really not a special event. Probably should be done at least as often as every other set of tires. Same for calipers and wheel cylinders. At least regular inspections. Brake pads and shoes should be checked for condition of the friction surface, not just replaced for wear. Glazing, cracking, separation, are other reasons brakes need to be serviced. Rotors and drums need to be inspected for surface condition and cracking. Brake fluid is also a service item that should be changed every 2 to 3 years.
