Results for "hydroboost"

Around my neighborhood, opinions on hydroboost fluid seepage are all over the map—my neighbor calls it normal wear, the RV dealer screams safety hazard, and YouTube mechanics can't agree either. It's not a major leak - just some dampness and staining where it mounts. I'm remembering a previous forum discussion where a user named Subford had similar seepage years ago and wanted to follow up on their experience.

The seeping seems minor right now, but I'm worried it could suddenly get worse while we're on the road. I had attached a picture similar to one I saw in an older forum post. Should I stop driving immediately and get it fixed? Or is some seeping normal and okay to monitor?

My main questions: Is minor hydroboost seeping immediately dangerous? Did Subford ever end up replacing their hydroboost? What does the replacement job involve? I want to be safe but also don't want to panic if this isn't urgent. …more

Pulled into the driveway and my husband pointed out that our 1997 Ford F53 motorhome's brake lines look like "spaghetti thrown at a wall" and now I can't unsee it. I'm working on brake lines for my 1997 F53 motorhome chassis, and like a true amateur, I forgot to take a picture before disassembly. Classic mistake, right?

Now I'm staring at this brake line wondering if I've got it routed correctly. It looks awfully cozy with the caliper - maybe too cozy for comfort. I'm pretty sure brake lines aren't supposed to be BFFs with moving parts, but I honestly can't remember the proper routing path from the master cylinder.

What's the correct way to route these lines on an F53 chassis, and how much clearance should I maintain from the caliper and suspension components? I'd rather ask now than explain to my insurance company later why my brakes decided to take an unscheduled vacation! …more

Between the small hydraulic leak that started on my 1995 F53 hydroboost brake system last month and what's happening now, I'm wondering how much worse this nightmare can get. Right now it's just a slow drip - maybe one drop per minute - and I can feel the power steering is slightly stiffer than normal, plus the brake pedal requires a bit more effort than usual.

What I really need to understand is the theory behind how hydroboost systems operate, since this is different from the vacuum brake boosters I'm used to. More importantly, if this leak gets progressively worse and I don't address it immediately, what's my worst-case scenario? Will I completely lose power steering and power braking assistance, or would I still have manual control of both systems? I'm trying to figure out whether this is something I need to drop everything and fix right now, or if I have some time to plan the repair properly. …more

Looked under the hood of my newly purchased RV and discovered the previous owner left the F53's external power steering reservoir with three return lines in absolutely terrible condition. They all clamp onto separate fittings on the bottom of the reservoir.

I'm trying to figure out the right way to flush this system. Should I be disconnecting each return line one at a time from the reservoir and doing them separately? And if I do that, do I need to cap off the reservoir fitting where each line was connected so it doesn't just dump fluid everywhere when I'm working on the other components?

Or is there a simpler approach that'll get all three components clean without all the hassle of disconnecting lines? …more

Spent the weekend troubleshooting my 1996 Ford F53 motorhome's spongy brake pedal, and now I'm really concerned about the hydroboost system safety. When I disassembled the unit, I discovered there's no check valve ball in the accumulator assembly. The system has been working fine so far, but I watched a video where someone's accumulator failed catastrophically without this ball and damaged other components.

I'm worried about operating the RV without this part, but I'm also second-guessing myself since the brakes have been functioning normally. Do most 1996 Ford F53 hydroboost units actually require this check valve ball, or could mine be a special variant that doesn't need it? I don't want to risk brake failure or cause expensive damage by running it incorrectly. …more

Since my 1995 Ford F-53 motorhome chassis started sagging badly in the rear, is this dangerous with grandkids riding along? The rear end has been gradually sagging lower and lower, and I'm seeking help with two specific needs.

First, I'm searching for a detailed service manual. I've already checked with a Ford dealership who recommended helminc.com, but they don't have the manual. I'm specifically looking for manual code FCS-12214-95 or something similar. I've also searched eBay without success.

Regarding the suspension, the rear is sitting very low. I'm looking for a budget-friendly temporary fix to raise the suspension. I suspect the rear springs might need work, and I'm wondering if additional airbags could help. My primary goal is an affordable interim solution that can prevent potential damage from low clearance.

I'm hoping someone with experience with F-53 chassis motorhomes from this era can provide guidance on both finding the service manual and addressing the suspension sag. What temporary solutions have worked for others in a similar situation? …more
