A Guide to Replacing Brake Hoses on the 2007-2012 Mitsubishi Eclipse
Understanding when and why to replace the flexible brake hoses on your fourth-generation Eclipse to maintain braking safety and performance.
- Check for the ABS recall (NHTSA ID 15V337000) on 2007-2009 models, as symptoms can mimic hose failure.
- Replace hoses in pairs (both front or both rear) for balanced braking; replacing all four is best for this age of vehicle.
- Symptoms like a spongy pedal, fluid leaks, or the car pulling to one side are serious and require immediate inspection.
- Upgrading to stainless steel braided hoses from a brand like StopTech can provide a firmer pedal and better durability.
Signs of a Failing Brake Hose
Brake hoses are wear items. Over time, the rubber can crack, bulge, or get brittle from age and exposure to the elements. An internal collapse can also occur, which may not be visible but can cause serious braking problems. Watch for these key symptoms:
- Spongy or Soft Brake Pedal: If your brake pedal feels mushy or sinks further to the floor than usual, it could mean air has entered the system through a failing hose.
- Visible Fluid Leaks: Brake fluid is typically clear to light brown. If you see wet spots on the hose itself, on your wheels, or puddles on the ground under the car, a leak is the likely culprit.
- Cracks, Blisters, or Bulges: A visual inspection can reveal the health of your hoses. Any signs of cracking, rubbing against suspension parts, or ballooning under pressure mean the hose is compromised and needs immediate replacement.
- Vehicle Pulling to One Side: A collapsed or blocked hose can prevent a caliper from engaging or releasing properly, causing the car to pull to one side when you brake.
- Brake Warning Light: A leak can cause the brake fluid level in the master cylinder to drop, triggering the brake warning light on your dashboard.
Known Issue: ABS Hydraulic Unit Recall
Mitsubishi issued a recall (NHTSA Campaign ID: 15V337000) for 2006-2009 Eclipse models due to potential internal corrosion in the ABS hydraulic unit. This could cause increased brake pedal travel and reduced braking performance. While not a direct failure of the brake hoses, the symptoms can be similar. The fix involves dealers flushing the brake system and, if necessary, replacing the ABS unit. It's wise to ensure this recall service has been performed on your vehicle.
Choosing the Right Aftermarket Brake Hose
For the 2007-2012 Eclipse, you have several good aftermarket options that meet or exceed original equipment (OE) quality. Aftermarket hoses are often more affordable than dealer parts and can offer performance benefits.
Standard Replacement vs. Performance Hoses
Standard Rubber Hoses (Good): Brands like Dorman, Dynamic Friction, and Raybestos offer direct-fit, OE-style rubber hoses. These are reliable, affordable choices for daily driving. They are designed to meet all federal safety standards (FMVSS 106) and provide the same fit and function as the original parts. While some users express concern over the country of origin for budget brands, many are manufactured by reputable companies that also supply major brands.
Stainless Steel Braided Hoses (Better/Best): For enthusiasts or those seeking improved brake feel, stainless steel braided hoses from brands like StopTech are a significant upgrade. These hoses feature a PTFE (Teflon-like) inner core protected by a woven braid of stainless steel. This construction prevents the hose from expanding or "ballooning" under pressure, resulting in a firmer, more responsive brake pedal and reduced brake fade. They are more durable and resistant to abrasion and punctures.
Pro Tip: When replacing one brake hose due to age or wear, it is highly recommended to replace them in pairs (both front or both rear). For a vehicle of this age, replacing all four hoses at the same time is the best practice to ensure balanced braking and prevent future failures.
Aftermarket Brake Hose Cost for 2007-2012 Mitsubishi Eclipse
| Part Type | Price Range (Per Hose) | Notes |
|---|---|---|
| Standard Rubber Hose (Dorman, Dynamic Friction, Raybestos) | $21.48 - $35.00 | Excellent value for daily driving. Meets all safety standards. |
| Stainless Steel Braided Hose (StopTech) | $50.00 - $64.68 | Performance upgrade. Provides a firmer pedal feel and increased durability. |
Frequently Asked Questions (FAQ)
Can I replace just one brake hose?
While you can replace just the one failed hose, it is strongly recommended to replace the hose on the opposite side of the same axle at the same time. Hoses deteriorate at a similar rate, so if one has failed, the other is likely not far behind. Replacing them in pairs ensures even braking performance.
What's the difference between a brake hose and a brake line?
Brake lines are the rigid, metal tubes that run the length of the vehicle's chassis. Brake hoses are the short, flexible rubber or braided steel sections that connect the hard lines to the brake calipers 🎬 Watch this guide on replacing a brake caliper and hose., allowing for suspension and steering movement.
Do I need special tools to replace a brake hose?
You will need a set of flare nut wrenches (also called line wrenches) to loosen and tighten the fittings without rounding them off. You will also need tools to bleed the brakes afterward, such as a brake bleeder kit or a clear hose and bottle, to remove air from the system. 🎬 See how to replace a hose and bleed your brakes. Standard hand tools like wrenches and a jack/jack stands are also required.
How often should brake hoses be replaced?
There is no universal replacement interval, but a general recommendation is to replace them every 4 to 6 years as preventative maintenance, or anytime they show signs of cracking, leaking, or damage. Given the age of the 2007-2012 Eclipse, original hoses are well past their expected service life and should be inspected carefully.
