Hi, My beloved RAv 4 51 plate delveloped an intermittent fault around 6 months ago, has now become a severe problem that no one can seem to pin down. It manifest as, from cold and and approx 2 miles into a journey a stange rythmic thudding grown louder and louder, seems to come from rear offside, first time It happened was convinced it was a puncture, stopped, inspected, no flat, re started journey, no noise, everything fine! IN short this has become increasingly frequent. We have changed the propshaft joint which was fine, have checked disks and handbrake, garage has checked it out too though of course it didnt 'perform' when they tested it. Definitely heat releated, brakes now squeak for first 50 yards from standstill, there's also a very loud clonk now from off side rear when cool. Always (so far) the problem fades away if I drive on... Could be my imagination but steering feels heavier. Convinved this is brake related, something binding or loose. Disks are not warped. Any suggestions gratefully received, Helen
Hey Everyone, I bought a red IQ 1.0 62 plate from a Toyota dealership in March, and have a couple of questions, I will need to buy new tyres, what would you recommend? I'm thinking on getting these but have read so many bad reviews that I dont know anymore. www.halfordsautocentres.com/tyres/continental-ecocontact-5-175-65-r15-84t Also, Since I purchased the car, one of the rear rotors seems to always be rusty, so I think that the caliper may be stuck? is this something I can get toyota to fix as part of the warranty? or will they just say its wear and tear? (even though its been like that since I bought it?) Is the process for replacing the rear rotors and pads the same as the front ones? (I've done the front ones on my Aygo, on a Vauxhall corsa, old ford fiesta, etc...) How does the handbrake work on the IQ? does it have shoes inside the disc like some BMW's? Any help is appreciated, Thanks, .
Hi All, I've been experiencing some issues with the brakes on my Corolla which I needed some guidance/advice on. The 'rolla is a 1.4 T3 spec with ABS. History November 2012 - Noticeable brake bind occurring so took it to the mechanic. Caliper slide pins on the front weren't as free as the could be. So he stripped all 4 brakes, cleaned and lubed them up and flushed the brake fluid with DOT4 March 2013 - Brake bind re-appeared and concluded the front driver's side caliper was seized. So the mechanic replaced both front calipers with re-manufactured ones October 2013 - After many months of trouble free brakes, I noticed some "potential" brake bind again. The main symptom being higher fuel consumption than normal. I took it to the mechanic again who jacked it up and checked if the wheels were spinning as free as they could, which all 4 seem to be doing so. He advised that as it was getting colder, it is possible the higher fuel consumption was due to the drop in temperature, which makes logical sense December 2013 - By this point, fuel consumption had got significantly worse. I was getting approximately 100 miles less from a full tank, doing the same journey and consistent driving style. As the calipers had been replaced, the next step was replacing the front flexible brake hoses, which the mechanic did. Present - After allowing the weather to get comparably warmer than 3 months ago and, giving the opportunity to test whether the issue was resolved with the replacement flexible hoses, the problem persists. Fuel economy is down up to another 50 miles less per full tank. I'm now averaging approx. 300 - 320 miles on a fuel tank. Prior to the problem occurring, March 2013 after replacing the calipers with similar weather, I was getting 450-470 miles from a full tank, doing the same journeys! I've recently taken it to 2 other mechanics for second opinions. I've fully described the circumstances and both mechanics think I'm being paranoid! So, monitoring the situation over the past 3 weeks here's what I have found, leading me to conclude there is still an issue with the brakes: Brakes appear to be reasonably free from cold. Shortly after driving into my journey (I'd say approx. 5 miles), the brakes feel as if they are binding, but not by a great deal. This is supported by the fact that on a shallow incline, the vehicle doesn't roll back, where as 8 months ago on the same incline, roll back occurred. After my journey, I 'feel' how hot the brakes are for comparison purposes. On a scale of 1 - 10 (1 being cold, 10 being Scorching hot) here's what I can consistently say:Front Driver's side - 10!Front Passenger Side - 6Rear Driver's Side - 3Rear Passenger Side - 5I did some research over t'internet (dangerous, I know!) and suggestions are the possible culprits could be: Possible ABS pump malfunction (although no ABS warning lights are on the dashboard whilst driving)Brake Master CylinderI'm assuming (again, dangerous I know!) that because of the heat differential, I may possible be on a diagonal brake circuit? I need some advice on what your thoughts are on what the root cause of the issue may be? Anyone had a similar experience and manage to resolve the issue? Any help/advice would be greatly appreciated.

Hi All, I just swapped my Surf for a spanking 2001 1.8 VVTi and it has a few problems that I'd like some 'educated' advice on. I have a binding front drivers brake and I am at a loss to reason why! I have stripped the brakes down, cleaned them and applied copper grease to the slide pins, support plates etc. I've checked the pistons and they seem to be ok and moving freely, albeit a little stiff but they look to be in good shape. The drivers side seems to be constantly rubbing as if it hasn't disengaged from the disk properly and the disk is getting very hot after a short journey. I know this happens when the pistons are dodgy and sticking but they seem to be ok and moving as per expectation, am I missing something? Someone said that the brake flexihose may be perished, is this a possibility? Also, when pulling away in 1st/2nd gear there is a low grumble/rattle/rumble from the front passenger side, any ideas what this could be? Thanks! Gary
