My '00 has a fair amount of rust on the brake lines. How can you tell how much is too much. I hate to think how much it would cost to have all of the brake lines replaced.....
View 2 RepliesI've got an '88 Volvo 740 Turbo Wagon: 5-speed, 225K miles, that's been acting up over the last year. She doesn't burn oil (qt in 1500 typical) and appears to still be tight. The Turbo works and bearings make no noise. The engine service light does NOT glow (but I admit I haven't checked the bulb). I do have a Haynes manual and have been using it to assist with some results (see replaced items), but I'm not trained on this car and this manual is woefully lacking in good diags for some obvious things. (IMG: [URL] .....)
Symptoms: She cold starts OK, but try to restart warmed at all and she usually has to sit at least an hour or no go. Outside temp seems to make little difference. There's a gassy smell while cranking warm and it's very much like a flooded carburetor engine. Often, the engine will finally catch with the pedal floored after a long crank. Also, after warming and driving a few minutes, the idle erratically will not return to normal, sitting up at 1800-2700 RPM for a bit before finally calming down. It was also running a little rough. There's a fair amount of carbon at the exhaust pipe and MPG is only ~20 and I'm a light foot. The idle RPM varies a bit much moving around between 600-1100 RPM warm.
What I've done this year: It had a broken thermostat (replaced), failing alternator (replaced), failed starter (replaced), failing fuel pump (replaced with filter), recent oil change (has turned black after 800 miles). Most grounds around engine and firewall and 12 volt ignition contacts cleaned. The bat cables were cleaned and terminals coated. Ohm tested the injectors OK (all exactly the same, on spec) and they all "click" in operation. I replaced a bad coil (low ohms by 20% for both primary and 2nd) and changed the carbon fouled plugs (which were also ill-gapped by some hamhand), both of which worked for the roughness considerably. The plug wires all came up roses well under 10k ohms. The battery was a suspect for testing low so much when resting, but the alternator seems to have slowly fixed that (and problems come when system is charging OK). However, the main warm start and idle problem persists. (IMG: [URL] ....)
My next good guess: An obvious rich condition exists and, having eliminated quite a few other things, a sticking "Air Control Valve" seems the likely suspect (some call it an idle control valve but I'm going by the manual). My specific observations of this device: after a warm no start, I pulled the ACV electrical lead and she fired right up and idled well at 16-1800 RPM. I plugged it back in and she chugged and nearly died before idling ~800 RPM. As it idled normally, I pulled the rubber hose from the upstream air connection to the ACV and it chugged and died within 5 seconds. I noted the vacuum was very strong. Putting the hose on, it wouldn't restart till I removed the electrical lead again. The ACV circuit has continuity at the device but I haven't ohm tested it yet. My best diag is the mechanical part of the ACV is gummed up or worn out. The Haynes manual was almost no way in arriving at this conclusion. (IMG: [URL] ....)
I have a 94 Ford Ranger 4x4 4.0 V6. It has developed a rough idle and has lost i fair amount of power. I cleaned the maf sensor and iac valve. Along with replacing an o2 sensor that was reading bad, with no improvement. The guys at O'reilly took a look and think I may be dealing with a timing issue or a warped valve. My question here is to found the culprit? I'm very inexperienced at working on vehicles and am damn intimidated by the scale of a project like timing. I should add that while traveling on the highway in high gear at low rpms, it develops a rough stutter. I can either power through it or ease off to get it to stop, but it resumes shortly after. It almost acts like an egr valve stuck open when on the highway. But that doesn't account for the rough (a consistent put, put, put...) idle.
View 4 RepliesI picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.
View 5 Repliesseem to be losing brake fluid from the area of the ABS system and it dripping down on the brake lines underneath. Noticed this when draining excess oil from the engine (dealers!!!!). I'm thinking this has been leaking a long time. I have the worst luck finding a reputable mechanic anymore and if I can't trust a dealer...
View 9 RepliesI just had my 10k service and noticed my two front tires still had a significant amount of brake dust and the rear tires did not. I always have more brake dust on the front than the rear and was the case when I dropped the car off. The service guy said they rotated from front to back but that didn't happen. I was under the impression they moved front to back and vice versa. What is the standard rotation for tires at the prescribed service intervals?

My 2005 Sierra, with only 42,000 miles on the odometer, has been stricken by the corroded brake lines syndrome. So far, only one line has burst - a line to the left front brake - spraying brake fluid all over the exhaust manifold and leaving me with rear brakes only. I'd like to know, before borrowing a car and heading off to the parts store for a generic length of pre-flared tubing, what the tubing diameter is (i.e. 1/4" or 6mm) and what the thread gauge on the fittings is.
I am going to be changing my brake lines in the rear and to the rear of my X. i ordered the rubber lines. what i would like to know is the part number for the steel axle tube line and the line that runs the from from front to back.. I don't know if it matters but when i looked up the left caliper line I had to get it for to 12/20/99...

View 1 RepliesHave 1995 Honda Accord with apx. 231,000 miles and needs all new break lines under the car. Honda Dealer states 12 hours of labor at $100 per hour. Should I go elsewhere or sell the car for $600 to the parts guy at the dealership offering to buy it since I wont pay the cost at this point to fix the car? Gas lines are all fine underneath by the way - I asked them to look since they could go next I would assume.
View 6 RepliesIs it a do it yourself job to replace brake lines. Never done it before or even seen it done. Special tools required? Will the auto parts store know exactly what I need? Are these questions answering my question?(don't do it) ...
View 14 RepliesOn my 1996 explorer it has 2 brake lines that come out of the master cyl, then they go into the anti lock, then 3 lines come out of the anti lock. We replaced some bad brake and now have those 3 that come out of the anti lock mixed up. Which one of those 3 goes to the back?
View 6 RepliesBlew a hole in the 3/16 inch line to the rear on the left frame rail, behind the gas tank. Lost all brake function.
Got the truck home and inspected. The line was rusted bad about 6 ft long from the connection at the rear hose to the axle, up to the rear seat area ( crew cab). From the drivers seat forward, the line looks very good. The line across the rear axle from left to right looks very good. I bought two 50 inch standard lines 3/16 inch. Started at the rear hose connection 6 inches behind the gas tank and ran forward to the rear seat area.
Cut about 32 inches of the other 51 inch line and connected and ran forward to below the front seat area. There is a metric connector at this point. I cut an inch in front of it to eliminate it. NAPA sells a high psi compression fitting ( steel , 10,000#) that you can connect two 3/16 inch lines together. I did that under the drivers foot area. I have done two different 2002 F150s in the last year due to this failure. Something to look into. Not nice to loose brakes in traffic.
If your worried about the steel compression fitting, don't. I have used these on several cars and trucks over the last 15 years. Make sure you get the STEEL high pressure compression fitting. Total line replaced on CREW cab, 51 + 32 inches. Pops right back into the original plastic clamps.... I might mention, that is where the failure was, under the plastic clamp at the rear end of the gas tank area.......... crud must collect on the clamp.
My wife has been letting me know that the car has this grinding-like noise only in the morning when she leaves and it's fine for the rest of the day. I did some google-ing to find that this might be due to thin layer of brake rust and the initial 'grind' is just it wearing off and why we don't hear it again for the rest of the day. It happened this morning and we did get rain/snow yesterday and she drove home in that and once home hasn't touched the car till this morning. The last time she mentioned this I think it snowed the day the car was parked. I drove the car all last weekend and didn't notice anything, but it was also dry out. Is this something that I should be concerned about or something to be aware of on a new-ish car?
- Recently had the 7.5k service done (1/30/16) and both brake occurrences happened after this
- We park in a climate-controlled garage
- Car has about ~9k miles
- wife took a video ....
Have to replace both rear brake lines, I can't find any information about doing the job. I need to know what size the lines are and what type of flair is on the ends?
View 2 RepliesJust have a quick question. I am replacing some rusted brake lines near the gas tank. I already have the rusted ones cut out. I want to know if this junction box is really needed. If not it would sure take out alot of bending the lines. It looks like the line only come down the frame and bolt into the block and then straight out to the rear wheels.

I have a 1999 Ford F-150 4X4 w/4.6L V8 W code, I recently lost all brakes. The primary line from Master Cylinder to ABS Pump rusted out completely. Replaced them but the other lines from ABS Pump to wheels are looking real bad. So I need to replace them, however I have no idea what the routing system looks like. Looking for a 97-03 F-150 Brake Line Diagram? I live at the jersey shore... so yeah rust is extremely common.... unfortunately.Also, where to get line assemblies?
View 7 RepliesIs there a good way to bend brake lines without a bender? I have two brake lines to bend that are probably no longer then 3 feet and don't want to buy a bender.
View 6 RepliesI am having trouble big time getting air out of my brake lines. I put new front pads and rotors on and also had to replace the brake line coming from the caliper as it kind of crumbled and needed to replace the next line up that goes to the ABS block on the left front. After doing this, I bled that wheel only and at first it was ok until the brake line on the right front at the caliper also broke when I was pushing on the brake pedal with the truck running, spewing fluid all over. I have tried to bleed using a decent vacuum bleed setup from Advanced Auto but keep getting massive amounts of air coming out and when I start the truck and hit the brake pedal, it goes to the floor. Could the master cylinder be bad? I have checked every connection that I made and all other connections and there are no leaks at all. I am stuck in the garage! The truck is a 1999 F150 4x4 with 4 wheel ABS.

View 3 RepliesWhat happens if or when you get air in your brake lines and the air gets into your ABS pump/module? What are the symptoms? Anything other than a soft pedal? My ABS module keeps thinking one of my tires is sliding when i am driving and pulses my pedal and i am at a loss.
